Can you describe the Radio audio quality improvment you have notice ?

On mine, when driving, I face 2 issues :

1/ some time the sound is crappy and the radio is almost impossible to hear. Then it could improve and if not I decide to change of FM station

2/ some time the AF (Alternative Frequencies) is quite "brutal" : when he loose the signal (or detect poor signal), it try to find alternative frequency for the same station: but it then jump from alternate frequency to an other one (some time there are music on these alternate, but these are clearly other stations !!!), then comes back to the original one : it's a mess the head unit has to change the frequency to test the quality. On my orginal Renault radio, it was doing this in the background and was changing frequency only if quality was better and whitout any glitch on the sound.

Has anyone installed 8259P UI02v1280x720 v81_(04/27/2023)? Are the errors of the TOMTOM that the instructions are not heard with the radio corrected?
[Android Head-Units] Marko055:
The sound quality of radio app is better, though it is as you described, AF is just shifting around, but that is whole other functinality compared to Aduio Quality.

For most of the time I am using AndroidAuto, HeadUnit Reloaded app to connect to phone, and use Spotify, as it gives the best and clear sound quality.

To whoever considers updating to v81 AND is a default launcher enthusiast (like me): v81 offers a limited amount of "themes": the first four from here (v61)

plus a new, comparably annoying one.
[Android Head-Units] pctjune:
Hi everyone.

I am considering upgrading to v81 to get improvment on the FM Radio quality reception.

Before doing this and as a général question before my possible first update, I just would like to get a confirmation : is this a one way update ? No way to do a fall back on a previous version if this v81 brings new issues ?

Thanks

One question, for this system, to play music in mp3 files, I don't like the native mp3 player, when put several albums, the albums and artist manager is very complicated, how could I change the player? or it is change the shell for other like agama.
[Android Head-Units] TorstenH:
You can use the mp3 player of your choice. But to open it via the steering wheel keys AppSwitcher is a must have:

[Android Head-Units] pctjune:
I made the same report. I installed the free "Musicolet Music Player" app and it's much better. I am not sure you can replace the genuine Junsun player on the "Home Page" of the Junsun Launcher.

In // I also put Agama as the Launcher to replace the Junsun Launcher. You can customize Agama to select the player you want, so it also solved this issue.

Hello my radio keeps going on to the main screen and off again after 5-10 seconds... Then it restarts again. I have the following adapter. Can it be that I have to swap the yellow + cable with the red ACC cable
[Android Head-Units] TorstenH:
You can swap B+ and ACC without the risk to break anything. So give it a try.

Additionally it may be the best idea to ask ACV and ARS24 (if you bought the adapter there) if they have an idea what the root cause could be.
[Android Head-Units] Dave822:
OK thanks I would try it. Or have a other people the answer

What is the pinout on the radio
[Android Head-Units] BoiaMondo:
Hi guys!

I'm eager to update my radio because I found out that even with a big subwoofer, the bass frequency is locked at max 60hz, in fact no lower bass come out from the headunit, I've tried using any of the 3 outputs but nothing changes!

I currently have the firmware in the attachment, and the headunit is a V1 pro 4+64gb: is the firmware in the first post compatible? How can I update it?

Build number:

[Android Head-Units] le_mi:
@Dave822

Die einstellungen stimmen mit meinen überein. Hast du wirklich nur die canbus einstellungen geändert oder noch etwas anderes? Hat es vorher funktioniert?

Switche mal auf die vorherige canbus einstellung und schau ob das radio da funktioniert. Du kannst auch verschiedene automodelle in den canbus einstellungen versuchen und schauen ob es funktioniert.

The settings are the same as mine. Did you really only change the canbus settings or something else? Did it work before?

@TorstenH

Long story short, I bought a 2011 w204 Mercedes Benz with a 12.3inch Android Mtk8259 with Benz GUI installed by the old owner, ancient software, read the forms here a lot and eventually installed the latest firmware

8259P_军灿UI02v1280x720-国外_v81_20230427.zip,

it installed fine but only to find that my resolution is 1920x720 and the GUI only filled half of the head unit pulse the software is too generic and missing a lot of functions and of course, couldn't get the cam bus settings for Mercedes Benz, anyway, I have installed this update

8259P_宝马UI02v1920x720-国外_v77_20230129.zip in the same time I have searched and found that JingTian Auto have a head united almost identical to mine with a lovely mbux GUI with all the bells and whistles for Mercedes Benz but its for MTK8581 and after almost 2 weeks of begging and nagging over ali express chat that my unite is there and I need the firmware update and to simply get rid of me they sent a 1.57g zip file (BZ_OS_8581_3.07.zip) which is the latest firmware and I'm dying to install it but the zip file structure is totally different and its almost month now and I'm getting frustrated and begin to hate the hole dam thing so I really need your help

how to install the provided firmware or make a .upd and .pin files out of it, and if not since this firmware is for 8581 where I can get the latest mtk8259 firmware for Mercedes Benz

and I'm very sorry for a very long post

[Android Head-Units] pctjune:
Hello

I am facing the exact same issue with release v51, and was hoping the v81 could improve as someone wrote earlier the radio was better. When you say you are running the latest, you confirm this is the v81 ?

What look strange is that it seems it start the TA SEEK (Tunin Auto ?) when it detect the signal is weak, thus this continual jump and crappy noise before it stops when it found a correct signal.

On my legacy Renault, it seems it was searching backup frequency in the backgroud as it was able to change the frequency for a station whitout any interruption and it was completely smooth and transparent.

I do not know of this is a feature of the Radio Chip or of the autoradio software : if this is the second, maybe Junsun could improve their software ?
[Android Head-Units] luis_rtm:
Yup, using V81, I do not observe any sort of improvement on my side and actually I am having some BT issues, so I may roll-back. Radio keeps jumping frequencies. I'd assume that a better developed firmware could handle the received signal better, but to be honest I don't know much about the topic to have a solid opinion. But this is a recurrent complaint and Junsun seems unable to improve it at all. I have tried 3 different antenna amplifiers, similar results with all. I feel tempted to box it and put back the original radio. It really get's into my nerves... slowly but surely...
