Hello, I did a r-link 2 configuration reset with ddt4all in my kadjar car, then I had to open the car door without restarting the system, then the car was locked, I opened the car, got on the screen.It's a black screen, the radio is working, but there is no screen, the keys are working. I'm display activated with ddt4all. Thank you

Try to simply restart the system with a long press of the On/Off button. It might solve the problem.

Hello, I had the same problem. I found the solution and I will explain below how I solved it. But after the reset, when I wanted to make a phone call, there was no sound from the car speakers, my voice was not going to the other side. I could not solve this problem and found a solution in the authorized service. I hope you don't have this phone call problem.

After turning on the screen, there may be a problem with the hand controller not checking the rlink, not turning on the sound, you may have problems with the rear view camera, you may have problems with the dials or parking sensors not working. I can help with solving all of them, but I could not fix the problem with only the phone call myself. Maybe there will be someone else who can solve it.
