Good evening, I'm Emanuel from Italy ... through Aliexpress I purchased an android stereo for my Fiat Bravo from 2007. The Stereo is a 9-inch MEKEDE mod M400 with an Intel s9853i cpu 8 cores + 4 Gb of ram + 64 Gb of built-in rom Audio TDA7851 ... Everything works perfectly, excellent quality but unfortunately the controls on the steering wheel haven't tried many configurations without result. Together with the stereo I was provided with the canbus control unit of the Bagoo model Fiat - BG-01 .... can you help me ??? is there any update ???

THANK YOU! I have just created account to write this. I was going mad trying to solve this problem, at first I thought that can bus decoder is bad.
Hello everyone. I'm from Germany and I don't speak much English and I work a lot with translation. I apologize for that. I bought the radio but I only have problems with FM radio. it just finds 2 channels, everything else is just hissing. there's a solution for that ? I've already tried changing the antenna, but the problem is with the radio. and I would like to deactivate the reversing camera at R because I don't use it .. can someone help me with that. Thank you for everything.

What car do you have? VW?
Maybe reverse camera can be deactivated in factory settings. Google if you don't know how to enter factory settings. If that doesn't work you have to cut the REVERSE wire.

I think, you need Antenna booster for the radio.
I've just bought booster and finally my radio can received many channel from none (without antenna booster, I cannot receive any single radio signal)

I also remember reading on 4pda that some VW, Audi need this adapter to power the built-in adapter. I couldn't find the post but I found these on Amazon similar to the ones mentioned above:

You never said what kind of car you have. Whether this is required depends on your car.
My car has a 12v connection in the harness for the amplifier in my antenna. I attached the 12v wire on my harness directly to the 12v as I found that the voltage on my head unit was a little lower.
For your car, if there is no specific connection in the harness, it may need one of these adapters to send the 12v through the antenna wire for a built-in signal amplifier. You can try asking the car dealer service or parts department also. Or try a car forum for your car make and model to see if they have additional information.
The A190 link above lists that it works with the following cars:

I have a polo 6R. The antenna adapter in the head unit YT9213AJ seems to have a booster. So I connected the 12V wire for amplifier to it (I don't have an external amplifier). On the other end there is only one FAKRA plug into one of the dual FAKRA socket.
The radio can pick up more than a dozen of stations, but none of them sounds stereo. Until I found there is a "Car Amplifier" button when the top bar is pulled down. It's disable so the antenna booster never worked.
The FM signal strength (RSSI) can be checked by the MTK engineering mode app. It went from -80 to -50 when the booster is working.
I'm using this device to strenghten radio signal. It works.
Hi!
I got an Audi A3 8P from 2010 and installed this HU. Everything is working, Android auto / radio / GPS / canbus / OBD, the "only" problem is the audio quality is horrendous. I was expecting it to be worst than the concert radio but it is really bad to the point I'm thinking about returning the head unit. I want to try to improve it before returning it because I was in a friend's car with the same head unit and the sound quality was miles away. I'm pretty sure the problem is hardware/connections. I read somewhere that some Audis have rear speakers amplified and front speakers not amplified. I'm not sure if my car has this configuration but that can be related to the problem.
What is happening is that the sound feels like someone is pushing the gain to the extreme. High/mid frequencies are very uncomfortable and the low frequencies are almost non-existent. I feel like the 3 speakers from the front are being pushed hard and the 2 front door speakers are very low. I saw a video (in Russian with awful translation so could not get much out of it) where the guy was saying that the TDA 7851 amplifier chip usually has too much power for factory speakers (he was not talking about Audi in particular). I spoke to Junsun and they told me they would look into it and try to find the solution but in the meanwhile, I asked for more specs. If I cannot find a solution I will return the hu.
I leave here some technical specs to see if anyone in this forum is able to help me. If I find a solution where I have to replace some speakers or get an amplifier I don't mind. I was thinking if it is possible to get a non-amplified output from the head unit and connect it to an amplifier that distributes for the other speakers.
Audi A3 8P
5 speakers in front and 2 speakers in the back
year: 2010
Head Unit: Junsun V1 pro (I will not post a link because I'm not sure it is allowed)
8-core / 4GB / 64GB
Radio chip: ST7708
Amplifier chip from the head unit: TDA 7851
DSP / RDS: Yes
Android 10
outputs: 4*45w
I found the first picture online but the interior is the same. I also leave here the wiring diagram, according to Junsun I just have to connect the main bay and then 2 RCA's for the rear speakers and 2 RCA's for the auxiliary input.
Thanks a lot for your time
I have the exact same symptoms in my audi tt mk2. As i had no experience with the oem radio i just assumed it was the car that had bad sound and bought an under seat subwoofer.

Thanks for leaving your input.
Did the subwoofer solve the problem? I want to test with another speakers to see how the sound comes out of the junsun head unit. Also I will try to take the car to a friend who is able to measure what is coming out of the unit channels. I will report back.
The subwoofer addes base, which made the sound good. But would not call it excellent, just good enough that it doesn't bother me.
Maybe try the DSP and play with the subwoofer low pass frequency adjustment, it may be filtering out the low frequency to send to a non-existing subwoofer.
I just installed a junsun android car radio. The problem is it doesn't turn off when the ignition is off also I can't find car settings.
Does ant body have a fix.
My truck is a 2011 f150.
Help is needed
