JY-UQS80N4G-GT update and Zlink fixes

[maxizozo]

Hello, I would like to know if there is an update for my unit JY-UQS80N4G-GT



Zlink is not working (Zlink service unavailable) and I want to know if other ROMs are available because I need Android Auto





Is it possible to replace the actual ROM (new interface Snapdragon 625 CPU) with an old ROM and old interface? (Maybe a ROM for UIS7862 units?)

I want to remove the black screen when reverse (No video signal) because I dont have camera

I only need beep sound for front and rear sensor (because I hear no sound when doing reverse approaching to other cars)



Please help me to fix this

Thanks a lot

Ok so Joying Europe helped me, to remove the reverse black screen saying "No video signal" if you don't have rear camera, cut the orange wire from canbus to connector.

And for reverse beeping sound (front and rear snesor), just plug in the provided speaker in the joying unit box (little round speaker)

Citroen C5 X7 with RT3 radio from 2008/2009 are complicated, and the only way to keep the reverse beeping sound for front and rear sensor is to plug the provided speaker

You will not have the reverse beeping sound in the car speaker
