Info screen, climate control and stereo were not working. When I would start the car the Infiniti symbol would sometimes show up in the info screen, then it would go back to startup. A few times it stayed on long enough to get the CDs out of the changer, then it started all over again. The Infiniti dealer traced this back to the CD/stereo assembly.

Can someone tell me which part in the assembly is causing this? There is a white electrical box on top, a CD changer, and then another collection of electronics in the bottom of the assembly. I got a used one from a wreaking yard and everything works except the CD player. I would like to swap parts around and get everything going.

Thanks in advance.
