Hello all!!

I am dealing with a weird problem with my RTI sat nav in 2007 C70. As i start the engine the RTI display rolls out and in about 10 seconds it rolls back. From this moment on I am not able to start the RTI sat nav nev neither with buttons on the steering wheel nor by remote control... In order to start the sat nav again I have to stop the engine, lock the car, wait for about 3 minutes and than start the engine again..

I have tried the "service menu", updating the system, cleaning DVD, nothing worked..

Any ideas?

Thanks in advance...
