hello can anyone help please,
i have a RNS510 1t0 035 680 B, a few weeks ago it started shutting down and starting back up randomly, when it is shut down you can still hear noise coming from inside.
when it started happening more frequent i deleted the firmware and tried reinstalling a few different firmware versions, but due to it shutting down so much during the install it wouldn't go past at most 65%
after doing this so many times it now will not go past the welcome to volkswagon screen and it still shuts down!
can anyone tell me what the problem is and how to fix it? my reading of forums leaves me to believe it is the mainboard. does anyone know of anywhere i can get it repaired to?
your help very much appreciated, many thanks
