I replaced my ICM, as the tinting was pealing so bad I could hardly read the screen.
So here is the issue, I replaced the tinting on my digital display on my dash and when I started the car up, the radio worked fine and for about 5 minutes and then cutout and then came back on and was fine till I turned off the key. Then next time it got worse and by the the fourth time it would play for 10-15 seconds and then cutoff for several minutes, I finally had enough and turned off the radio and ever since then it will not come back on.

So here is what I have done, I replaced the ICM with a used on and had it programmed and I got a loopback and put it on the Multi media module and radio would not come on, but my question is if the MMM controls the infotainment system, would the radio work?

BTW: Nav and bluetooth are not working either, which leads me to believe the MMM is bad, but is there a way to test it?
