Hello Phaetonauten, the following question to the community: The radio navigation system at Phaeton is already a bit older in software, which is why it takes a little longer for the system to come to life when you start the car. Which can sometimes be the reason why you don’t see a picture of the rear camera in the monitor, although you have been driving backwards since 17 3/4 seconds. Was so with all my faetons so far, BJ12, BJ14 and BJ16. Now I have with my current GP4 (this is the 16th) f Similar problem: After switching on you can see the welcome image (Welcome Volkswagen or whatever), but the computer doesn’t run up. After about 1-2 minutes the monitor goes off and after 10 seconds the system restarts. After 1-2 minutes the image goes out again and the system restarts. After 1-2 minutes welcome image the image goes away again and the computer restarts. Usw. etc. Follow: No Navi No music No useful phone. the steering wheel key select, call and call, but the hands-free device does not work, the participant can not hear you and the very best: as long as the ignition is one, you can not use the Händi either, because the SIM card is switched to third-party control. After 5 minutes, one or two hours driving time, it can happen that the radio suddenly wakes up and plays music again and all functions connected to the RNS810 (Navi, return camera etc.) again available or not. Then the RNA810 may only come back to life after the next pee break when the vehicle is restarted. Or on the day at all no more and only again the next morning. Now my questions: Has this strange behavior been observed before? Are there therapies? Is there any cure? or do I still have to hope for tomorrow’s spontaneous healing? For news, tips or even simply comforting words I would be grateful to you.
