Short story is that Pumpkin had me reset the system to stock. This caused me to not have radio at all (no static, never finding a station) and the physical "back" button does not work.
To my knowledge, I have messed around with all the settings possible (126 code, changed among 7 radio types on both American bands).
I installed Malaysk's latest ROM thinking that might fix it all, but it did not.
Does anyone know the correct settings or have any idea on what I can do to get things to work again?
Thanks

Looks like you updated with the wrong MCU image. If you have written down the original MCU code you can download a MCU image from this forum and restore your radio.

Oh, let's just pretend that I never wrote anything down. Where can I get info for the correct one?

Well, then, you're in a bit of a trouble. I would have said to contact your vendor but since they sent you the wrong files in the first place there's no guarantee you'll get the correct ones this time. It may be better to contact the vendor nevertheless and request a replacement unit since their software update caused the HU malfunction.

Actually, I stumbled on the solution this morning (I just hadn't had time to post yet).
I thought I was making alterations, but the stereo needed to be reset each time in order to actually apply the changes. After 15 permutations, I stumbled on the correct ones and now I have radio and correct buttons.

Pumpkin C0257.
Radio app not working!
Just a quick flash of the screen and does not start.
If I assign 'Mode' to a steering wheel button, I can hear the radio.
No screen nothing, just sound.
I've tried every setting I can think of.

Hidden menus - ANT Settings

While messing around with the hidden menus, I turned on PRX/DRX measurement display , under RF -> ANT Setting menu. There seems to be no way to turn the option off again.
Can this have any impact on battery life / performances? Is there a way to disable it? If i click again on the PRX/DRX ON button, it reboots the phone but the option stays ON.

I cant find a clear answer what this is for some say fm radio others say its how gear talks wi5h the fone. I hate to make an example here thought this is why we dont touch settings we dont know about. U hqve no clue what it does and for all u no u coulda wiped ure phone. This is a big no no but enough of that u way no matter how many times u click it stays on. Only other way would to restore ure backup or it may been on in the first place. Or a factory reset if no backups
you may look into ant+ its part of the system it may give you more of an idea ive never messed with it im pretty sure i got it debloated outa mine

ANT+ seems to be a communication protocol for data exchange between smartphons and various types of sensors.
On the other hand, "ANT settings", in the hidden menu context, seems to stand for ANTenna settings...
Did some research and I'm starting to figure it out a little bit.
PRX should be "primary data receive" while DRX is "diversity data receive" (it could also mean "Discontinuous reception" ....). Both have to do with LTE-WCDMA (?).
I'm not into telecom engineering, but I guess having both ON it's the way it's meant to be.
What is strange, is the menu behaviour : initially showing nothing, then apparently enabling both, and now allowing to turn off either one function or the other but not both at the same time.
For the time being, I see no anomalous behaviour or battery drain.
Bottom line : better not to tamper with it, I concur. But it would be nice to know what exactly PRX/DRX means , and if the menu is merely a tool for reading network performances ("lte ml1 serving cell measurement") or it actually enables/disables antenna features.
PRX is primary data receive signal.
DRX is diversity data receive signal.
You can guess the rest of it....

Joying 130 users, quick question. What is your keymap and touchmap in factory option

I'm having an issue w/ the SRC button not doing a thing so I'm curious what yours are set to. Also, does your source button work? here is a pic of the unit for reference.

Someone has to have one of these, help me out guys.

I think there's an xposed module that lets you reassign the buttons. What Rom are you using?
I have an Eanon GA2114 though.

Joying and the module and even logging don't show anything
I just installed this same unit today. When I press the SRC button, it toggles through the preinstalled Radio, Music, Video and AV In apps. I'd actually like to change these if possible. The factory Video and Music app aren't that great. I'd rather have it toggle through the apps I installed for these functions.
Can you do me a favor or two. 1. Go into factory settings and tell me your keymap and touchnmap settings? Also could you tell me the keycode that is displayed if i linked you to a program? You can uninstall it after, I really want to find this keycode.
If you don't use mtc-keys these would work:
This, this , or this
Thanks much,
Dave
I may need a walk through to get the information you need. Been an android user for a long time, but I'm a noob when it comes to these android radios.
But I'm trying to learn.
Vert - I'll grab a photo of my settings when I head back down to my car a little later today.
Thank you very much. Could you also quickly install this, open it, check my events, logcat and kernel and then press the SRC button and let me know what you see in the log? You'll the image below. You'll have to go back into the program as src will open one of your media apps.

Pretty easy. The touchmap/keymap info can be found in settings | factory settings | type 126 | and go to the tab that shows keymap and touchmap.
Dave
I exported the DMCU from the key settings tab in factory settings.
Its dmcu.cfg -- useful? Happy to upload.
It can't hurt I suppose. I'm not exactly sure what that file has but I'll research it. Did you have an import setting as well? I don't even know if I can decompile that DMCU.img file as I remember trying before. With that said, do you have this exact unit? Can you tell me what your keymap and touchmap option numbers are?
Thanks
Dave
if you could also let me know what MCU version you have.
Thanks

w0rdie any help?

Problem with Torque Pro background and EONON...

Hello,
I've searched all over the internet and can't find a fix.
I made some changes to a Torque theme to fit my BMW, but for some reason the background image never seems to adjust to the screen.
Is there a way to fix this?

What did Torque support suggest?
Nothing. I tried to post on the forum but my posts never show up.
Anyone? Please?

Assume you have paid for torque pro? How did you obtain the software?
It came with an Eonon head unit.
Is it hard to make the background image fit the screen?
it is a pirated version of torque and is probably buggy.
Suggest purchasing Torque pro from plays tore and then requesting support from Torque if unable to resolve the issue.
Trying to revive this topic.
It seems nobody knows the solution, including the author of the app...
He does not answer any emails...
Same problem with the forum and with the background image in my Torque app .
Torque Pro, full version, purchased from Google play.
Same problem with the forum. I can't see my own posts. No support at all.
There are several related posts, all unanswered...
Please somebody help
I don't know if this will help you but I just had a Android 8 head unit installed in my Mustang and It had an old version of Torque installed. I uninstalled it and then installed the most current version of Torque Pro and it fixed it.
PS
My Head unit is the Lexxson SP-AT2018-2G16

Canbus Management

I'm new to android radio, having looked but not touched for a long time.
I have a 2015 Jetta and for my birthday my family got me a Burger Motorsports JB4 (Piggyback tuner), and an XTRONS radio (PX5 8 core 4GB unit.)
The JB4 unit uses the CANBUS to keep track of engine parameters while it modifies signals between the engine and ECU to control boost, fuel pressure, and timing. Officially BMS says it won't work if you have other devices connected to the CANBUS and say it is due to bandwidth issues. If the JB4 detects that it isn't getting enough information across the CANBUS it defaults down to a safer tune.
I've discovered that as long as the radio boots after the JB4 they seem to play nicely together, for the most part. But this means the XTRONS software loses lots of settings every time I start the car.
I'm looking for a way to control what and how much the Radio uses the CANBUS for, I think if I could limit it to steering wheel controls and reverse camera I would be happy, or even just delay the CANBUS connection in the car for 30 seconds. The other path would be to flash a ROM that keeps all its settings when it is rebooted but I haven't seen that issue addressed in the HAL9000 or Malaysk threads.
Is there a way to modify what the CANBUS module is looking for? Would other ROMS tolerate being rebooted better?
Hi Profsnakes,
I am currently working on modification of some images in canbus.apk file
I am not sure you can get more from your car by just modifying the software, it depends mainly on the canbus adapter you are using
Have a nice day

Thanks for the reply. Unfortunately, I don't know or understand much about the development side of this stuff. I've worked as an electrical technician for years and have a good understanding of how a Canbus works but not the programming or design side of the stuff attaching to it.
Rather than getting more out of it, I was hoping actually to be able to limit how much it used the network somehow. Even just reducing how often it polls the network. The other device I have attached requires a constant data stream from the ECU.
At this point, I have narrowed the problem down. While it would still be good to limit the bandwidth used by the radio. It seems the error I was having was being caused by the USB connection between the radio and the tuner when the car was starting up. So far disconnecting the USB when the car is off and reconnecting after it turns on seems to keep it stable. I ordered a USB "KVM" style switch that I'm hoping will keep me from having to open the glovebox all the time.
Heres what I've got going.

PX6 Android 10 head unit Radio stops working.

Hello, i have a huge problem with my android head unit which i bought from Ali.
Everything works fine except radio. fm and am.
More specifically when i turn the ignition on, radio works fine and after 1-2 minutes it stops like it has no frequency at all. When i try to search for the next radio station it does nothing. All other functions work perfectly (Bluetooth, usb, YouTube etc.) . Now, in order for the radio to work again, i have to turn of the engine, wait at keat 5 minutes and then turn again the engine on. The radio then works again for 1 -2 minutes and is does the same thing all over.
I have already tried factory reset but that doesn't work.
hello all sorry that picture and my car stereo after android 10 update
the volume while listening to the music has become lower i.e. you start hearing at 25 instead before you started hearing at 11 does anyone know how I can fix it thanks

If it's a software problem, you can easily find out with NavRadia+, Basic is enough for the test:
NavRadio – Aplikace pro Android na Google Play
Vychutnejte si miliony nejnovějších aplikací pro Android, her, hudby, filmů, televizních pořadů, knih, časopisů a dalšího obsahu. Kdykoli, kdekoli a v jakémkoli zařízení.
play.google.com
Some radio settings are in factory settings (password126). In the Radio tab, set your region. In the Other tab at Auto search stop - DX - 20 db, try another value.
You have to detect the hardware problem yourself, it can be bad wiring, bad grounding, faulty radio chip, fault on the motherboard, the device is interfering with the alternator, led lights, some additional equipment, antenna....
Give it to an expert who will measure everything, but it is difficult to find someone for these devices.
