Volvo S80 2001: vin : YV1TS61P921244258
I have replaced the RTI DVD reader.

The new unit is working only to some extent.
I got the RTI analyzed by the local Volvo dealer.
The error code is: CEM-1A57 (communication error)

( the CD is read, my position is correct, the controls on the steering wheel does NOT work, I can control the RTI by remote control, the screen intensity is so poor that I cannot read it in daylight)

Please advice
