New Saab 9-5 (2010 on) / SAAB 95 NG Infotainment unit after replacement not powering up
« on: 04 July 2014, 08:52:50 PM »
Some month ago my local SAAB service centre performed Infotainment firmware update via USB .
At the end of update unit died.
It could because it was USA update and my car is UK version , but it could also be that during update TIS computer was connected and was not supposed to so that somehow interrupted update and killed unit.
End result , completely dead unit.
Anyway I got replacement unit, and upon installation Infotainment would not come on line.
It was clear that unit is powered , TIS computer could communicate with Infotainment, unit was also performing software update ( could see it on TIS computer) ,but screen was dark grey, in the same way when you switch on T V or Monitor but without video input. You can tell TV is working but no video signal is coming
Conclusion was it is faulty unit, so we got another one.
Upon installation , same problem again – unit powered but screen was grey as if no video input.
BTW in both cases no buttons under the unit or on steering wheel made any difference.
So either both replacement units are faulty, technicians are not doing something correctly or something else could also be wrong (ECU?)
Has anyone come across this kind of problem?
Any advice would be welcomed.
