My 2003 XC90 AWD radio does not work. It occasionally comes on when starting the vehicle, but only stays on for about 20-30 seconds then kicks off. The LCD screen never comes on. From what I've read, this is very common and I've seen videos showing how to change it that doesn't look too hard.
The problem is, while sourcing a used one, there are so many different ones listed and I have read that they can cause all kinds of seemingly unrelated issues if the ICM isn't the exact one you need.
Is there any way to know what years/model ICM would be compatible with mine?
