ICM3 problem (it doesn't work but sometimes works)

Hello,

I am a new owner of a Saab 9-3 1.9 TiD Vector combi 2006 from Poland. My radio (ICM3) worked perfect for about a week. Then it stopped working. When I turn on the ignition, the ICM3 screen stayed black and no sound was made. Moreover, the car consumed the power (discharging a battery) even when the ignition was off.

My mechanic checked the amp and fuses and they were OK. When he disconnect the ICM3, the power consumption stopped. He plugged a ICM3 from another car to my saab and this ICM3 worked. My ICM3 in other car still didn't work. He recommended buying a new ICM3.

However after a few days the radio unexpectedly started to play (sreen, navigation, sounds, everything) and there was no problem with consuming power (discharging a battery). Excellent!

However after another few days the problem returned. Now the screen is black again, no sounds are made and the battery is discharging.

Do you have any idea what is wrong? Am I supposed to buy a new ICM3 or is there any chance to fix it?

Thanks a lot!
Wojtek
