[Q] Bluetooth car stereo (JVC KD-BT1) works only on specific Android version/base :( - Desire HD Q&A, Help & Troubleshooting

Hi!
I have a car stereo with bluetooth handsfree included (JVC KD-BT1), but it stopped working a year ago or so. At first I was always thinking the car stereo is broken, because all other bluetooth handsfree sets seemed to work fine.
But when I tried an Android 2.3.5/ base 3.06.405.1-ROM, everything was working fine. I verified this by using several ROMs with different bases and so far, only Android 2.3.5/3.06.405.1 seems to work. Therefore my only choice at the moment are DeSense and Honeywonder3D.
It seems to be a problem of my car stereo, but unfortunately I couldn't find a possibility to do a firmware upgrade...
Maybe some of the all-knowing ROM devs have an idea on how to integrate the bluetooth package from the latest version/base to other ROMs, maybe somebody made the same experience with the car stereo and managed to solve it?

Hello,
i´ve got the same problem with this Car Stereo.
Did you find a solution?
I´ve got a Samsung Galaxy Nexus und Bluetooth would be great!

In car bluetooth handsfree

I am looking for some feedback on the various in car bluetooth kits that are available in the marketplace, ie the fully installed kits rather than the in ear jobbies.
I have a Pioneer head unit that offers bluetooth headset features however due to a design fault it is fecking useless, ie the mobile phone can't be within a metre of the head unit unless you are prepared for the caller to put up with terrible interference.
Admittedly for a normal phone this would be of a lesser issue as there is the facility to store numbers on the headset, but as I use a XDA Exec with TomTom, I need the pda where I can see it
I have used an in ear device in the past, but it is bloody annoying.
I have looked at the various Parrot kits, the 3000, 3100 and 3200 all of which would do the job, but I don't know how they fair in reality.
I have used a Nokia bluetooth kit, IIRC CK1W or was it CK 7W that appeared to be a litle flaky when trying to connect to the exec.
Whilst browsing eBay, I have come across these http://cgi.ebay.co.uk/SIEMENS-BLUET...6QQihZ008QQcategoryZ42419QQrdZ1QQcmdZViewItem ,http://cgi.ebay.co.uk/BLUETOOTH-HAN...7QQihZ009QQcategoryZ80085QQrdZ1QQcmdZViewItem http://cgi.ebay.co.uk/MOTOROLA-BLUE...3QQihZ018QQcategoryZ35190QQrdZ1QQcmdZViewItem
So does anyone use any of the above and does anyone have any recommendations?
Cheers and Happy New Year
I have been using a Sony head unit with handsfree, A2DV and AVRCP. Its been pretty good and I have no problems recommending it.

Would that be the MEX-BT5000? I'm considering getting it for use with my Wizard.
Yes, thats the one.
http://www.sony.com.au/xplod/catalog/product.jsp?categoryId=22000
Hi all,
Seems the most appropriate place to post this.
I recently upgraded my headunit to the Sony MEX-BT5000. It plays CD's, MP3 CD disks, has a good tuner and and AUX in. It also supports bluetooth profiles A2DP, AVRCP, Hands-Free (HFP) and Object Push Profile (OPP - for contacts) and as is supports A2DP and AVRCP (basicically A2DP but the remote control features) you can also play music from your MP3 player, phone or whatever through the stereo. It works fine with my M3100.
The handsfree calling is good and pauses the music when in call but there are bad points which I've not managed to solve yet such as inability to initiate voice dialing from the unit, the call button brings up a Sony phone menu. It also can only store 50 contacts and doesn't automatically sync with the M3100 like my Parrot CK3100 would. This means you need to decide which 50 you want to have on there. You can assign 6 speed dials to the 6 preset buttons on the front.
The sound from this stereo is far better than my previous Sony MP3 stereo and on this alone I would recommend it to anyone. It also comes with an infrared remote which allows you to digit dial, andswer and hang-up etc alongside all the basic stereo functions.
Hope this might help someone looking to buy something similar.

I've had the BT5000 since January, and use it with my Wizard. Its BT performance is the best I've ever seen -- it's the best speakerphone I've ever used.
Sony also has a new MEX-BT2500 unit that's about half the price of the 5000, with all the same BT functionality plus an aux jack on the front panel.
Parrot
I am using Parrot, both the ck3100 without the LCD and with the LCD, and since upgrading to Radio 1.15/1.18 have had no issues switching between them and my Jabra X10 BT Headset.

When I experimented with a friend's Parrot unit I discovered that it didn't retrieve the contacts from my Exec, and I couldn't do voice-dialling with it. It worked OK as a hands-free speakerphone but that's about it.
Was your experience better than this? If so, is this because you upgraded your Universal's radio stack?

Sorry for the late reply.
Check the Firmware version on the Parrot. You can download the BT updater from their site, and use it to upgrade the firmware of the BT Car Kit. I had the same issue, but after upgrading to the new FW, the issue was fixed.
I have this car radio too.
Works like a champ on my iMate JasJar.

JABRA BT320s

Anyone had any success pairing the JABRA BT320s with MDA 2 and if so, do all the functions of the bluetooth stereo headset work?
Thanks.
Upgrade
Purchased Jabra BT320s and paired with Vario 2 after upgrading ROM. Everything working fine with excellent sound quality. I did not try to pair with Vario 2 on old WM 5.0 ROM so I cannot say if the BT320 would work on this OS.
I DID try to pair a BT320s with my TyTN a while ago, no luck......im going to try again now, as i was quite annoyed it didnt work. Will report back soon.
EDIT:: Gonna need to get a plug adapter as i forgot the dumbasses i bought it from sent an EU power supply and not a UK one...LOL!
from what i remember it was around JUNE time when i tried it, sounds like the bluetooth drivers may have changed since i tried it but it did seem as if the headset was the problem and not the drivers as i have had other A2DP headsets working fine.
Jabra BT320's
Bluetooth can be a real pain at times - with unpredictable results. I cannot begin to tell you how much wasted time I have spent trying to pair gadgets together - so it was a pleasent surprise to find the Jabra's paired first time and functioned as described.
Wishing you LOL.
tange.
well i tried it again and even on my pretty up to date ROM it only pairs as a headset and not wireless stereo urgh!
may be worth a rom upgrade?
i have a 320s (uk version bought from a tmobile shop - their selling them for 25quid) and it works fine on my wm5 spv m700 and is detected as wireless stereo and headset

i had the same issue with this thing ... i did a hardreset and it showed up as stereo headset again. i had to do one anyway...
@all how do you like the jabra? mine is quite noisy ... i use my ugly samsung speakers instead and thinking about buying a 3.5mm adapter for the car.
I have been playing with the bt320s for a few days on different roms for my wizzard. I have been tring some WM5 and WM6 roms for features and bluetooth options. What i found was that I could pair with WM5 but even if it gave me the stereo option it was only in mono. After a google search i found someone mentioing that WM5 only supports Mono.
I then tried a couple of WM6 roms and found that they all supported the stereo correctly.
I then hit a problem as I decided that a ROM i tried earlier had everything i wanted (Diamond). So, decision made, I flashed the rom and tried to pair and it would only pair on headset and not offer the stereo. Very wierd as it worked before????.
I then found a post on another site which mentioned the following with the Bt320s headset.
1) delete any pairings on the phone.
2) switch of headset
3) plug the charge into the mains
4) put the charge into the headset 3 times for 5 seconds each.
5) Recreate the pairing with the phone.
Sounds wierd but it worked??????
I now have a wm6 rom with stereo bluetooth.
the only problem now is that WM6 closes all my apps when i switch it off and on using the power button.
This seems to be a bug when you enable a security pin in WM6 which i am forced to do via a directpush policy from work. Does anyone know a workaround for this as it is anoying to have your cub/pointui/media player etc close on you and go back to the home screen whenever I use the power button.
*****Orange are selling the Jabra BT320s online for £9.50 at the moment. Well worth the money*********
Quick update, on the latest pandora ROM (Tytn) ..... Its working great.

I posses a sgs2 with a bluetooth problem... I have no problem pairing or connecting to the car kit (pioneer DEH7350BT)
but when I do, and making/recieveing a call, I can hear the other side just greatly but the other side CANNOT hear me.... I have tried everything... and YES it do work with other phones (such as Se Naite, iphone 4 and etc) those other phones are working great with it (the other side CAN hear me)
but with my sgs2 it doesnt...
also sgs2 wont let me transmit music using the bluetooth...
any solution anyone? please? I have tried everything! pairing and unpairing, tried few diff roms, taking out battery, tried EVERYTHING...

I doubt it's that important you have to bump the thread every hour or so.
Unpair both devices completely and repair them again. It might not be pairing both modes.
You can also see if HFP is enabled in the /etc/bluetooth/audio.conf file via the Root Explorer app.
I use music and handsfree just fine with my SGS2 and my cheap Panasonic head unit. If the 2 options aren't there under the bluetooth device, then it's a pairing issue.
I have paired my device several times in various cars and never had to do any special configuration. I've always worked fine for the first try.

Does your phone pair properly with other car based bluetooth?
If not, it may be the kernel.
I had successful pairing with my original dlev rom in both of my cars and intermittent problems answering or my the other side could not hear my voice. Solution was to switch the kernel.
Hope this helps.
to what kernel you switched?! that exacly my issue! please answer
If you're having that much problem with it, pick up wired headphones with mic (or use the ones that came with the phone). I switched from bluetooth to these and will never look back.
but i need to use bluetooth due to the car's speakers....
thats the whole thing...
Bluetooth is car is always a matter of luck to me.
Feling lucky because I can manage it with my SG2 better than with my previous phone, the original I7000 galay
well that info isnt really helpful
anyone else might help please?
anyone????????
Are you 100% sure the car player has compatible a2dp music streaming?
If so then both headset and media options should be available in the Bluetooth pairing options.

Did you ever solve this issue? I am having the same problems with the same deck and phone.
Cheers.
It is not the phone, it's your dash unit. You'd be better off contacting Pioneer or whoever makes your aftermarket unit.
My SGS2 has sync'd and made calls perfectly via BT since day 1 with my Nissan GT-R... everything is stock Nissan though.

[Q] Car Bluetooth Audio Problem

I have a LG Nitro HD running on AT&T. The phone came pre-loaded with 2.3.5. The bluetooth phone part works as I can make and receive calls with my car (Suzuki Kizoshi 2010), but the audio over bluetooth doesn't work. The phone part works as I can make and receive calls. This is very important for me to be able to play the audio over bluetooth as I have a long commute to work and like to listen to my music. Any help is greatly appreciated. Thank You.
It's been about a month and still no solution. Has anyone else come across this problem?
I do not have this problem. I have a Pioneer X930BT headunit in my car and my Nitro streams audio over bluetooth (A2DP) to it perfectly as well as phone calls.
Have you tried streaming Sirius or spotify over bluetooth? I found that the only app on the phone that streams audio to my car correctly is the pre-installed audio app that comes with the phone.
I can confirm google music and napster stream great over bluetooth. I have not used spotify or sirius for android.
Are you sure your car supports audio profile?
I stream spotify, tunein radio every day through bluetooth.
Spotify actually pauses when bluetooth connection is lost which is great for getting out of the car. I wish TuneIn would do it.

I have had the same problem with my nitro, it will automatically connect the phone but the media (A2DP) seems to drop automatically after connection. I've found if I manually re-connect to the receiver both will stay connected.
(settings > Wireless & Network > Bluetooth settings > *tap device name*)
I, like you, use it every time I'm in the car so it's annoying but it's a fix until there is a valid solution like a update or properly built rom.
In your case I would delete all the phone profiles from the car memory and re pair them. A lot of cars have a seperate a2dp profile for streaming music and if you pair them seperately the car stereo thinks that it needs to be paired only with the cell phone while the phone says that is paired with phone and audio.
It is not a LG Nitro 4g issue. Updates/firmware would not fix it.

That seems to be your problem JoTomlin and Kaiser. Before I installed my new headunit in my subaru I had tons of issues with my captivate playing music over bluetooth because the car had seperate profiles for A2DP and handsfree. When I got my new headunit which has a single profile containing both A2DP and handsfree it all worked without headache on the captivate and now the nitro. This is a problem with your car stereo. If its anything like my subarus, it would prefer to connect to handsfree and it would have to physically disconnect handsfree to connect A2DP (I would have to manually connect via the bluetooth menu). I solved it by getting a tunelink bluetooth audio receiver so handsfree would connect to the stereo and to the tunelink at the same time. Eventually I got tired of that and bought a new headunit.
Apparently a lot of people have swapped out their factory Kizashi factory head units for something better. But again, you'll want to bug Suzuki about something like this.
FWIW, I can stream Pandora just fine over a VW headunit with factory bluetooth. I do have to sometimes to a reconnect/pair though.
Has anyone figured out this issue? I stopped using my Nitro for about 5 months and then just recently updated it with 4.0.4, but still have the audio issue. My Samsung Galaxy SII doesn't have this issue. It's frustrating because I really like the Nitro. The Bluetooth audio is a huge issue though. Any help would be greatly appreciated. Thank You.

[Q] Bluetooth A2DP issue with Car Stereo

Ok, so here's the deal. I have a rooted T-mo G3 (D851) on a stock rom, out of the box it's been awesome to use with my Pioneer AVH-X2600BT head unit in my scooby. I was messing around with themes a short while ago and then the bluetooth stopped working intermittently. From what I can tell the mix-rate of the A2DP stream changes from 44k to 3hz and all you hear are beeps at multiple amplitudes. The beeps are playing out of the buffer in the head unit until it empties then it resets the connection to the phone. It still plays out these beeps until it's empty even if I disconnect the phone from the head unit.
I don't have this problem with two other iPhones. And previous to my screwing around, it'd work flawlessly since a bought it (launch day.)
Could I have screwed up a mixrate setting someplace? I do have a custom mixer xml for boosting headphone port and speaker audio but I never touched the settings for the bluetooth driver.
This behavior is intermittent and it matters very little what content I'm playing through it. I do notice that when this is happening, no metadata or control is capable through AVRCP either. (i.e. Pandora app can't connect to the phone, no album art, etc)
Sometimes it'll stop doing it and play normally for the rest of the session (drive) after a few minutes and everything is normal. Sometimes it doesn't do it at all and sometimes I can't get it work normally at all.
Here's a video showing the behavior:
http://youtu.be/qYuuTG01x1E
Reset your Bluetooth on your headunit and pair it again with all your bluetooth devices.
I had a similar problem with my LG G3 and my Pioneer AVH-8500 where my Pioneer will not recognize my LG G3 anymore but recognizes my Note 3.
I fixed the problem by resetting my Bluetooth on my Pioneer and had to pair all my devices back to it again.
You will have to look into your Pioneer manual on how to reset your bluetooth.
Edit: I just remembered something.
Did you happen to update or change your firmware.
Some KitKat firmwares are missing the Bluetooth Metadata and will not function properly.
Use autoaudio download it from playstore. This fixes my problem on metadata
Hey thanks guys.
I reflashed the bt radio in my head unit and the problem so far has seemed to go away. Metadata and everything works again.
I appreciate the heads up from another pioneer user.

How exactly did you reflash the bt radio? I have the same head unit and am having problems with it dropping the bt connection to my G3
I just got forced to upgrade my LG G3 to Android 5.0 and it completely screwed up my Bluetooth audio connection in my car.
Bluetooth sync to home audio playback is fine, but BTooth audio is completely corrupted with the Pioneer AVH-X2600BT.
I cant find the instructions on how to reflash my stereo firmware to reset bluetooth settings. I cleared my bluetooth devices in the stereo setup, but to no avail. Can you point me to instructions on a reflash?
I am having the same issue. I have 2 other bluetooth devices that my G3 will connect to and playback is fine for as long as I have battery life. But when connected to my Pioneer AVH-x2600bt, I get constant skipping after 2 minutes of playback. I can pause it for a couple of minutes and when I start playing again it's fine for another 2 minutes. I have done a hard reset on the Pioneer and reconnected my G3 but no change. I have unpaired and cleared all of the bluetooth data in my phone and reconnected, no change. All of the Kit Kat OS devices I have still work fine with the Pioneer but none of the Lollipop devices work. I emailed Pioneer, their reply was for me to take my deck to a service center. That will do no good. One of two things needs to happen, Google needs to update their bluetooth firmware or Pioneer needs to update the firmware for the AVH-x2600bt. Until one of those two things happen I guess I'll be using stone age technology, an auxiliary cable.
Thank you, that is all.
Hello
I can't sent the music to my car radio according to the version of Android. In version 5.0 with different kernel that doesn't work, and with 5.1.1 (blisspop) it works. I 'm preferred the custom rom because I like some features. Someone have a solution or an explanation of why?
