Q:I have a volvo xc90 2003mod. A few days ago the display went black when my iphone charger touched the 12v cigarette lighter “output”.
We have checked all the fuses and measured that the 12v is still working.

The display is black, no sound and no light. Parkingsensor sound is also gone.
AC controll, cigarette 12v, DTSC button and everything else is working. It seems like it is only the stereo that will not work anymore.

A friend told me that it might be the “ICM”. What do you think? Will this part might fix the problem, and is it just to replace or will I need something else also? (Sorry for my english)

A:please check all the fuses before you replace the radio, if you need ICM there are 2 types high performance and premium sound please let me know which sound package you have and also if you have car phone
