Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit

[Coconut_Drift]

Anyone figure out how to get the radio working with fcc launcher. Or figured out how to intercept the "mode" steering wheel button functionality? Would love to be able to remap it or at least add third party apps to the rotation.

Hi guys

I just purchased A Junsun v1 pro 8gb+126gb With UI 3.0 for my 2005 touareg
Everything is working quite nicely but the sound qualit is weird i do have really low bass .. I tried to play with the equalizer and so but its getting worse

My car have 10 LoudSpeakers and no external amp

Sound is coming clear from every Speaker

I had much more bass with the oem head unit as i had too much if the bass was set to max

Also

I can't find the VW boot logo ?? Is there a way to import manually some logos ?

Thanks

by the way, there is no reason for you to root the headunit, you will get no real advantage.... just do not bother and risk bricking your unit.

Thank you very much for your answers, problems A) and E) are resolved.

For F) (iGO, offline navigation) I prefer Navitel, but according the product page
"
Junsun has pre-installed offline maps and is permanently free to update
>>About map update:if you want to update the map, please contact us, we will upload it to the "Drop box", please do not download in other places, otherwise it will damage the original map. Update map time : once a year
"
So I've just contacted support, we'll see.

As for the GPS issue: the case is not that the GPS module drops satellites, but android drops the GPS module itself. I think at least, and this is the reason for seeking logs and software reboot and GPS restart solutions.
For software reboot rooting looks inevitable. Lots of risk for marginal benefit, so I'll just leave it.

Hi guys.what is needed to have canbus functions in my car?

Hi guys!

After using ~6 months the 4GB+64GB PRO version I'm pretty happy with it, but I couldn't say it is perfect at all.
I face some problems with it, and I'm curious whether it is just my luck or are they general. I'd appreciate any feedback or way of fixing if applicable.
BTW the problems seem to be FW independent, currently I use 8259P_军灿UI02v1280x720-国外11_v1_20220323.zip and it only shows minor design changes and for example hides search option under android settings, but made no perceptible functionality or stability improvement. I use the default launcher btw, did not root it yet.

So the problems I worry about, and related questions:
A) "start the last used media app automatically" - it is very annoying, is there a way to stop doing so? Do I need to install another launcher for that?
B) GPS. It often fails to start, but in seldom cases it stops mid-drive. It's not about finding satellites; the sole cooperation between android and the gps module does stop. (Without root) I'm sure I can't even stop and restart GPS. Is there a simple way to get logs what actually happens?
C) Wired AutoLink connection is unstable. It often drops connection and reconnecting is tiresome and sometimes neither possible. Tried with two cables and two phones. Is there a way to get logs at least?
D) Wireless AutoLink never worked for me, though there is an option for that in its settings. Looking up the product page there is now an updated picture stating the 4/64 model supports only wired carplay / android auto.
E) Is there a working software reboot solution without root? And with root? (I wasn't yet brave enough to try out what the reset microswitch does.)
F) iGO map updates. In theory one can request yearly one update, but never tried. Any experience? Is it personalized? It's been more than a decade ago when I dug into iGO and installed maps, POIs and stuff.

Thank you in advance!

Assuming you have the 4G version of this head unit. My unit had AutoLink hidden but I was able to enable it in the "engineering" settings (accessible by 8878). The problem then became that AutoLink requires an activation license for Wireless CarPlay. I was able to purchase the license by changing my region to France and adding a fake address in France. Nothing is shipped, it is all digital, so address does not matter. Try purchasing a license and putting that into AutoLink and see if it activates wireless CarPlay/Android Auto. Make sure you get the CarPlay license if that is what you need. Android Auto does not work if CarPlay license is activated. Vice versa.

I'm having two issues with my Junsun Pro V1 4G 825X 6GB/128GB. It won't save apps that I save to the launcher. I'm using the BMW CIC version and if I select an app for it to keep on the Navigation, Music, Bluetooth main screen, it will forget it when the unit powers off. Any way to make these changes persist?

Also having an issue with Wireless CarPlay phone calls. I can't hear the other person but they can hear me through the microphone.

I've received somehow a bonus Android Auto so activation wasn't really a problem.
Also, just yesterday evening I did exhaustive testing and found out that the reason behind my stability problems is the cable. More particularly two cables, which I've been testing with earlier. A third one seems to be working just nice. Fingers crossed.

Any help?

So that the radio does not start every time, you have to activate the sleep mode on the radio, to do this you have to go to the configuration, within settings, car infotainment and here in about the device, in the gear wheel that appears enter with the code 8878, and in the first option activate sleep mode.

Well mine has soldering issues inside antenna. I've disassembled GPS box (broke the glued parts) re-soldered cable to the PCB and glued again. Initial behavior was same. Intermittent disconnections leading to GPS signal drop. Now working ok.

Some questions and some answers for some.

Using Junsun V1Pro (4GB+64GB) for more than 6 months.

1. RESOLVED: Major issue was poor BT microphone quality. - Solved by reading here in XDA forums, attaching external microphone and most important - unsoldering internal microphone (separate board under the buttons connected with 6line flex cable to main board). Quality gone from 2/10 to 8/10.

2. Wired CarPlay - working again intermittent after several connection/disconnections of the cable to phone. sometimes works straight from the beginning. Probably will purchase CarLinkKit v2 to get CarPlay fully wireless. As also charging on this USB was pathetic.

3.AGAMA launcher - launcher cannot see "Phone Link" that starts CarPlay, neither as internal application like Radio nor like external app - like Waze.

4. Camera - using some cheap camera which I'd like to replace with something wider and with greater resolution. Does this head-unit supports AHD cameras and how to configure it ?

5. RESOLVED: GPS disconnections - resolved by disassembly of the GPS box and soldering cable again.

Do you have any recommendation / aspect to choose the particular external microphone? Or maybe a link for that particular topic you mentioned?
I still hope that the latest FW update will fix my GPS problems. If not I'll crack it open and have a look at the solders. Thank you for the hint.

Has any one come accross a problem with reversing camera where the image from camera is B/W ??? I bought a new AHD/CVBS 720p reversing camera, installed it, everyting works, but the image has no color.... I suppose it is a problem with PAL/NTSC, but for the love of god I cannot find the corresponding setting... Thank you

No recommendations I've tried two different ones that are both Chinese, one came with the unit one purchased separately. one has double resistance than other and both work fine when tested no significant difference for the other party.

About GPS. I've installed a small app "GPS tester" or something like that that shows current satellite info and tried to pull/push cable where it enters GPS box. Interestingly in my case when pulled connection was OK while when left alone satellites were lost.

Sleep mode was already activated but it still shows car and android logo each time i turn on the engine
