HIZPO Offering Quad Core A9 7" w/ Android 7.1

https://www.amazon.com/gp/product/B01JULCTYE/ref=ox_sc_act_title_2?smid=A17YHR60ETNWLC&psc=1
Thoughts? Thinking about ordering one.
I just returned a headunit from ATOTO because it worked like crap.
I like the prospect of 7.1 and offline maps already installed.
Quadcore vs Octacore I don't think makes a huge difference here.
Would love to know opinions.

I have a similar product to this with the product ID "B071LT7LC3" on Amazon. (I cannot post links yet) From the looks of things, my unit is likely the same hardware as yours, only with a different front panel and added DVD player. This is the information I read from the device:
MCU version: MTCD_XRC_V2.52_1
Build number: px3-userdebug 7.1.1 NMF26X eng.hct.20170527.145603 test-keys
Kernerl version: 3.0.101+ [email protected] #550
Model: px3 (800x480 O)
I sadly managed to brick mine by running an incompatible root method for Joying devices via Wireless ADB. I have not found a root method actually works on these units yet. If you are looking for an Android stereo that you can root, look elsewhere. I got a copy of the firmware from Hizpo, but not even that can fix the damage I did to it. It is with this warning I hope to prevent you making the same expensive mistake.
Note that you cannot use these units with a PC via USB, you must use Wireless ADB using an app. Use "126" to get into your factory settings and play with those, or "adbon" to enable debugging. You can also download a Development Options app to reach those settings, as they are hidden. The various methods of recoveries, including the one provided by the seller (Hold down the power button, turn on the power to the radio, release after 5 seconds and wait 30 to reach the recovery), did not seem to work for me either. It is possible I corrupted that too, but I am not sure.
I will happily share any other opinions I have about the unit if I ever manage to get it unbricked.

FYI - there are literally 1000s of different MTCD units by about 10 different manufacturers, they all share pretty much the same hardware and the software is interchangeable

But certainly not root methods and certain firmwares. Pick the wrong one and you can brick your device beyond restoration - to the point where the recovery does not work and no firmware update worked to fix it. I had to get a new unit.

Yes, all RK3188 MTCD units are the same inside, they use the same SoM and ROMs ARE compatible as long as you get the screen res and processor type correct and even if you get the screen res wrong its no big deal, it wont brick.
However if you flash the firmware from an MTCB unit, or from an entirely different, unrelated unit , its sounds like this is what you did.

I was looking at this, but when I noticed it said PX3 I decided to skip.. Doesn't make sense to not have the PX5 chip.
Now if there was a version with a PX5 on the new os Id be interest.

Sure the PX5 will be fast, but the PX3, especially with 2Gb of RAM is perfectly good.

If you decide to order, please update with your impressions. I too tried the ATOTO M4 garbage head unit, and it has almost encouraged me to give up on them entirely. If you find this one to be worthwhile, with it being at a similar price I might give it a shot.

No need for him to post impressions - its an MTCD unit and theres a whole forum about that you can read to see what theyre like :
https://forum.xda-developers.com/android-auto/mtcd-discussion-questions-development

Ordered this unit myself. I'll share thoughts after I get it.

Installed, and I'm definitely impressed. Very zippy and sounds great.

Gotcha, just got confused since you asked what MCU version. I thought all new units are shipping with MTCD.

No, not all units are MTCD, I ve heard a rumour that a company is working on MTCB/C N, even if that is untrue then you can still buy MTCB/C units.

That I know. You can still buy KitKat units..

Recommendations for an Android based Double Din head unit with navigation, backup cam

Hi everyone!
Wondering if anyone can point me to a decent/good no-name head unit? I have a Ford explorer with a double din opening. Looking for something on the cheaper side but don't mind paying extra at all if it's money well spent.
I work for USPS delivering mail so it would be REALLY NICE to if I could somehow load a route into navigation and have it run from the head unit instead of my phone. Have had problems finding something that works decent even on my phone but think I've found something that sort of works. I am a sub so I'll be learning and helping on many different routes over the next few years and this would be a tremnedious help untill I get the route memorized! Otherwise I wouldn't even worry if it was just one route.
Would also LOVE LOVE LOVE it if I could make the unit become a DVR for a dash cam. Support for multiple cameras would be a huge bonus. But I'm also thinking a dedicated backup camera with DVR support would probably work better...maybe!
Could careless about CD capability.
I've never played with one before to be honest but really hoping for one that can be rooted. I have pleanty of experience with phones and tablets. (I am on a grandfathered unlimited data plan so not worried about data.)
Would also like to consider name brand units if anyone knows which ones are Android based. Alpine is my favorite and don't care much for pioneer but will def consider it if it'll do what I need it to.

I just purchased yesterday a Pumpkin 8.0 direct from their website (autopumpkin.com). Sounds like we are looking for the same functions - navigation, cameras, etc. I am installing this into a 2008 Toyota Tundra, and found the need for a backup camera as soon as I bought it. You didn't define "cheap", This unit is $310 including shipping.
Another unit i considered is the xtron TE706PL. A little cheaper at $290 on Amazon. Both units are 4G ram and 32G rom. I went with the Pumpkin because I wanted the volume knob.
Best of luck in your hunt!

Any update on what you choose and performance?

I have owned an universal Dasaita HU and highly appreciated. I also recommended to my 10 friends to upgrade their entertainment system with Dasaita. They all really enjoyed.

Is there any dedicated app for back view camera of android head unit? Having camera settings etc

dasiata vs xtrons px6 new to android head units

hello, not new to android been modding for many years but this will be my first jump into a android head unit. this will be for my wife's car and she wants the dash to remain stock and anything wider then stock will partially or fully block the middle 2 main ac vents. so she limited me to the standard 7" screen size.
im looking at the max6 and one from xtrons px6 version which does not have the dsp chip but they offered me the chip if i buy the unit from them included.
im reading of some issues with the max6 here at xda and wanted to know if that is the norm with this model? and how is xtrons overall these days i was reading they were decent but those threads seem to be pretty old and i dont want to revive them. otherwise is there any specific model px6 7" unit anyone here can directly recc to me? any help would be appreciated. ive spent hours reading all sorts of threads but many of them are older threads now about px5 or px3 units.
also does anyone expect anything new from ces this year chip wise? though i dont know how many of these china companies show there. i sawe dasaita has in the past.
thanks!

I grabbed the xtrons tq709ipl because its got the px6, is known to be compatible with some roms here, and the price was better than dasiata's comparable px6. Like you mentioned the xtrons doesn't have a DSP, i'm not an audiophile so i don't really know about features I wont be able to judge. What I've read is that the chip in the xtrons even without a DSP is still "better" than most name brand head units out there. amazon is running a $20 coupon right now too (as of 2/19/202), so that was nice. Shipping from hong kong only took 3 days too somehow, so that was cool.
With either of them be prepared to modify the double-din dash kit if you need one for your car. The android head unit faceplates are a few mm larger than North American big brand units like pioneer, jvc, sony, etc.
Good news is I've read enough to conclude all px6 based units are essentially the same guts, and roms will generally work on any of them. So you should just decide: what faceplate you like better between the two, does the DSP really matter to you, and then look at cost and how quick you can get it!
Good luck!

Purchasing - Looking for advice on avoiding scams

Hi,
As per title, I have decided I want one of these HUs with the RK3399 and the MTCD/E MCU. I plan to flash with a custom ROM as soon as I have tested it and before installation.
History: had a Joying 10 inch a few years ago, hated it, want to do it right this time!
The vehicle (in my case) is a 2009 Toyota Prado 120 (similar to the Lexus GX470) RHD, The units I am looking at are full ctr console replacements with fascia and vertical screens.
After wading through the seemingly endless mire of Aliexpress listings and producing a shortlist, I am still a little overwhelmed and confused; prices and specs seem to be all over the place and in many places are contradictory. I'm an eBay kid, I have hardly used Ali before.
Of course, once I shorten my list a little bit more, I will get in contact with each seller to verify hardware specs and make sure I'm getting excatly what I am paying for.
So to help me (and maybe others having a read!) I have a few questions to help me filter out the 'too good to be trues' and the outright liars.
1. Hardware - does the fact that the unit has a RK3399 mean it is definitely a MTCD/E MCU?
2. Hardware(again) - does the fact that they state PX6 necessarily mean its a 3399?
3. Resolution - I have seen all manner of resolutions stated here... the most common seems to be 1024*760/600 but there are a fair few listings saying 1920*1080... which definitely piqued my interest. Is this an outright lie or is it possible that they really do have 1920*1080 displays? (my guess is they're listing it as a "yes it can display 1920*1080 content" and not necessarily actual screen res.)
I would love a true 1080 display but it's potentially too good to be true!
4. Screens - What specifically (if anything) should I look out for/ask about in relation to the screen? model number? some say IPS, some don't.... Are they all the same? (they certainly look pretty similar!)
5. AliEx stores - If anyone has any honest stores they would like to suggest I'm all ears(eyes?) Or even other outlets to buy these things? (eBay doesn't have much listed for my car) The stores I am shortlisting are ones that have decent ratings (obviously) and have been established for more than a year.
6. Anything else? tricks for new players?
Bear with me - its a solid chunk of cash and a decision I will have to live with for some years!
Yes it's my first post - have used the forum over the years for all sorts of information, hopefully I can give some back!

I'll have a go at answering some of your questions, but I'm fair new to this whole Android head unit game so if I'm wrong someone will hopefully correct me.
What was is it specifically about the Joying unit that you hated that you hope will be addressed by a new unit?

1) MTCD/E are MCU's manufactured by Microntek, but there are other manufacturers of MCUs out there than can be paired with the PX6, so there is no guarantee that a RK3399 means that the unit is fitted with an MTCD/E MCU
2) My understanding is that the RK3399 is a generic SoC, PX6 is a verson of the RK3399 specifically tailored for use in head units.
3) I don't know, but I would be wary of anyone claiming 1920 x 1080
4) Not sure
5) I bought a unit from Dasaita on AliExpress. It definately wasn't straightforward (first unit was sent to some other destination, they had to send me a replacement via DHL). But they did at least try to get things sorted ina timely manner. I chose Dasaita (aka hot-audio) mainly because they do post here on XDA. They are also on eBay, but the prices on Ali are better.
6) The aftermarket service from Dasaita leaves something to be desired, but from what I can see, none of them are very good at this. But I guess that's the price you pay for buying a cheap head unit. Overall, I'm very happy with my Dasaita PX6 unit, but i've only had it installed for a month, so early days.
Anyway, I hope that this is of some help to you, and good luck with your search!

Hey thanks for the reply!
The Joying unit was likely my own fault for not doing enough research prior to purchase, paid too much for too little I guess.
It worked well for a while but progressively got slower until it was nearly unusable for anything more than a clock and radio, this was quite a few years ago though and I had not found any alternative firmware at the time, I eventually just formatted it for some minor improvement and sold the car anyway.
With this new unit I will be running hal9k from the start instead of the default firmware and am expecting fairly smooth operation. It will be used for offline raster maps while I am out in the bush
Thanks for the information regarding the hardware, I still had a few grey areas in my mind there so that helps clear a bit up.
I wanted to use Dasaita as they seemed to be recommended but they do not sell to suit my model.
I will start making some enquiries today and see if I can get any clarification on those 1920 displays.
Cheers!

I hope this is the right forum.

I apologize if not. I'm desperate for assistance and I hope someone can point me in the right direction. I recently purchased a Dasaita Vivid 10 on Amazon for my 2015 Camry. Few things:
After installation and turning it on, I wasn't presented with the first time user setup. Additionally, there were a few local MP3s on there. Specifically "Hotel California" from The Eagles. Is this normal or was I sold a used unit? The unit itself had the plastic on the screen. ZERO marks that it was used. Everything from my perception was brand new.
However, when I went to connect WiFi, I received the seemingly common error of it turning on and instantly back off again. As such, I did a factory reset. This erased all of the music that was on the device. This leads me to think that it shouldn't come with music...
Each time I turn my car on, the WiFi is a red X on the icon on the bottom right. To resolve this, I need to hctreboot the thing using factory settings. After this, it will work. However this really sucks and I don't want to do this every time I get into my car. Last night I changed the BT setting and I believe it may have fixed the wifi issue. However, this broke Bluetooth. When I loaded up a hardware info application, there was a mac address for WiFi but none for BT. Is there a way to know which module I have to select the right setting?
Can someone explain exactly what I can do to fix this? After searching for hours I am so lost with all of the terms. Vivid, Scout, MAX. I have no idea where to even get a firmware file. What does MTCD stand for? While it may be considered a budget radio, $530 bucks is a big chunk of change for a radio to be this unreliable. I wrote on Dasaita's forums and it looks like they couldn't care less to assist people. Frustrated, and I'd like help here before returning this and returning to the stock unit. I can provide pictures of anything if needed, just let me know!
Thank you all!

Welcome to the world of cheap Chinese origin Android head units and quality issues.
There is no first run, that is normal.
MTCD refers to a type of unit based on HCT design. There are a bunch of factories that produce these and a bunch of resellers, such as dasaita that sell them, applying made up brand names and model codes. Dasaita appear to price their units at a premium.
Suggest returning it for the hardware issue and look to an FYT based unit, which might get you closer to what you want.
I no longer recommend MTCD based units, and have since brought an FYT 7862UIS based device. The bugs are less, superior hardware, fantastic audio and works without all the mods/hacks.

Aww man, not the news I wanted to hear however it was expected. At this point I might just go back to stock. I really loved how the dasaita fit into my Camry as it looks super OEM and clean.
Do you know of any of the FYT units that look OEM for a 2015 Camry?

Is this FYT: https://www.joyingauto.com/joying-1...radio-replacement-2015-2017-android-auto.html

I have a 2017 Camry and have this head unit:
https://www.amazon.com/SYGAV-Android-Toyota-Carplay-Navigation/dp/B08PKZY28H/ref=sr_1_1
While it's not a FYT unit, I will tell you that it does not have Vivid installed on it and has worked quite well in my Camry for over a year now.
Would be happy to answer any questions about it. I posted a review on Amazon and have answered a few questions over on Amazon as well.
