[FYT Android Head Units] eduarcor75:
Hello guys,

I would love to have this post here for future reference for people with the same car and kind of radio, as it could help them in a way.

As per some comments I read already, I know that some people here would say that Junsun V3 plus, is not a FYT radio, but I do not agree. Even part of the interface/menus of the radio is exactly the same as Mekede/Teyes... and I have the feeling that it really is, as I see a lot of things in common with the software with Mekede and Teyes. EDIT: just my confusion, I was implying some people were saying it was not a FYT unit, but I was not understanding correctly. It is a FYT unit!!

CONTEXT

So let's start with a brief story of how I end up here.

My girlfriend wanted a new radio for her car after having the experience with a rent car, with all the carplay bells and whistles. So we had a look good offers from Aliexpress and we found a model she liked for very good money, and the brand was Junsun (Model X7 4G, in a VW Polo). My girlfriend uses iphone so she wanted carplay (wireless) and in this radio works like a dream, specially with a widget in the homescreen (image below) that directly shows the carlink app which connects to carplay and see the small screen there (by default I think the widget points to google maps instead carlink, but can be changed). So overall very good experience. Except Junsun support, as their help is pretty much useless.

The UI is excellent, everything needed is in the home screen. Is perfect layout wise (design wise is just OK).

When my father saw the radio he wanted one (so he bought a Junsun V1 Plus 3D in a VW Passat).

Both units worked very well with no major issues at all (with canbus functionality, perfect car info and steering wheel control, etc..). Obviously, I was the one debugging and making it work, as they come with zero instructions and their support is, well... non existent. They have little small issues, but acceptable.

So obviously I was the next one :)

Then I wanted to buy something for my car, an Audi A3 8P (2009) restyling.

I tried several years ago (2016) to put one, but end up returning it for some problems. So I started reading a little more for radios in general and specially for my car since it could be potentially more complicated for its speakers configuration (will comment it later).

So after researching a little and realised that there are a lot of radios which look exactly the same but in numerous brandings. I thought that potentially could be pretty much the same hardware with slight variations, and didn't matter too much what branding are you getting, and are the software and support is what pretty much varies from companies.

And I end up here in this forum, reading the FYT Android Head Units.

OPTIONS

Reading here in forums a while ago, I researched and what I liked was:

Mekede V7 plus: https://es.aliexpress.com/i/1005006584279752.html

Teyes CC3: https://es.aliexpress.com/item/1005001645113257.html

but both are quite expensive.

Mekede specs:

Teyes specs:

So, with the previous experience with Junsun, I though it could be a good idea (LOL) to buy a V3 plus 9.5" (which is VERY VERY VERY near to both Mekede and Teyes, hardware wise).

I think the only thing which does not look the same is the amplifier of the radios, but for the rest it seems to be pretty much the same. So I bought it recently.

Specs:

I bought it very cheap (€250 8gb/256gb with free shipping) with some aliexpress discounts that are happening lately in aliexpress, and it arrived home in less than a week.

But now there are a lot of problems. And Junsun support is USELESS.

PROBLEMS

So let's enumerate the problems.

1) Audio does not work properly in the rear speakers.

The audio is very loud, so I don't think there will be a problem with volume here.

So for my car (A3 8P) which in most of the brands states:

If your car has the factory navigation/BOSE system, the rear speakers will not work after installation and you need to buy and audio converter to make it work.

With or without BOSE, have 10 speakers with subwoofer, tweeters, etc... but is different how the amplifier works, etc... As I interpreted that as I don't have BOSE system, I wouldn't need it, but I think that is needed either way (in fact I read, I read comments of people in Aliexpress (in the converter product) saying that you need 1 converter if you use normal system and 2 converters if you have BOSE system.

I am very surprised why they don't say you MUST buy one for sure, no matter what system you have.

Without any converter, It looks like it works in one of the rear speakers but not in both.

I hear as well, pops in the rear speakers while restarting the radio. And sometimes I heard some noise while changing from one app that uses sound to another one... Like from music, to radio, or from some apps which makes sounds on top of the current song/radio.

I already bought the mentioned converter (I bought one which looks exactly the same as the one they sell, but at almost one third of the price).

What they sell: https://es.aliexpress.com/item/1005005181807545.html

The one I bought: https://es.aliexpress.com/item/1005006003149527.html

Let's see when the converter comes.

2) Canbus with no car info

The canbus work with the steering wheel buttons but there is no car info at all.

The reverse car signal with dynamic parking lines that can be controlled with the steering wheel -which is very cool!!- is working, so clearly the canbus is working, but shows ZERO info about the car. My girlfriend's and father's units, work like a charm with all the info of the cars, etc... Not mine.

Talking with Junsun, as usual they think I am stupid and I am not able to know how to open the application car info and see the info... And after waiting the whole weekend (as they said they had to ask the engineers), they replied today saying that the engineers said that the car info is not supported for my model (WEIRD, it does not make sense). I know that Audi A3 was supported by any brand with a canbus.

I have the feeling is just a software issue. But I have no knowlege in android units.

3) Home screen widget issue

I love home screen radio interfaces. It potentially can change the whole experience of usability (I am software engineer, but don't work with UIs).

One of the main reasons to buy the radio was because I liked the interface, like my girlfriend's polo I find very useful to car the Carlink app in a widget in the home screen:

View attachment 6114403

As you can see is a widget to the upper right in which you could put another app inside (I would prefer to be much bigger, like my girlfriend's). We can call it Picture in Picture widget maybe?? By default google maps is the app loaded, there is a way to load the app you want, but when I try to load CarLink, it is not shown in the lists of the allowed apps you can add here. So is it not supported??

I have the feeling that the image of the attached here, in which you can see Carplay working there (as per the iOS icons), could be a retouched image, instead of being a real image. Cause you could see that is a little bit stretched... I can confirm that the image I shared from my girlfriend's car reference is correct and works like a charm, you can change the app to Carlink and use both Carplay or Android Auto with no problem at all.

When I asked Junsun about it, they replied: You can try and long press the carplay apk to move it to the location you want to place it.

It obviously does NOT work.

Wish to be able to use the interface of my girlfriends radio in this one.

4) Boot logo and anim boot

Would love to have a way to change the boot logo and the boot animation. I don't see anyway. Junsun is clueless saying:

If someone can translate to me? Saying "settings" 3 times in the same sentence to say nothing. They are just clueless...

5) Stability issues

Apart from that, I see some stability problems here and there, like the radio search does not search properly (I think I read in the forums here that Mekede has the same problem).

Sometimes the previous mentioned widget, when I use it with google maps it just freezes and when you change the screen to another app, and when you go back is not there, is empty... Is just very weird.

I have the feeling that this is one of the first iterations of the software, and is still not very stable.

I haven't experienced any of these problems in my girlfriend's and father's units.

OTHER FIRMWARES, SOLUTIONS AND FUTURE POSSIBILITIES

I have seen that in this forum some firmwares from Mekede, and Iying. Which is great to have as possible options.

I have read that someone already asked in a thread if it was possible to install Mekede's firmware on Junsun V3 plus, and someone replied it wasn't. Here: https://xdaforums.com/t/junsun-v3-plus-fyt7870-firmware.4673657/

Is there any possibility to modify Mekede's firmware to make it work for Junsun V3 plus?

I volunteer to give any info needed to see if we are able to make it work (without risking the unit to be returned). I think the unit looks good, and the quality is as good as any other of the brands we mentioned here. Obviously, I think has to be polished but if the mentioned problems can be fixed, I think is a great choice.

Obviously if it is not possible to fix the issues I would return it, but I would love to give it a try before.

Sorry for the big chunk of text, but I would love to document the whole process properly and give the proper info for anyone who may need it. I hope I express myself properly and organised the information well to be followed. Sorry as my English is not the best.

I hope someone here could give me a hand so I can keep updating this thread accordingly, as I think may be a great help for others too.

Thank you very much guys
