Hi,
My other half has her 6 disk changer in the dash, and it seems to be pretty unreliable with CDs - we have tried the obvious things like a cleaning cd, but no joy. it seems to be worse when the car has been sat in the sun for a while, but it can be just as bad when its cooler. is there anything you guys would recommend trying before scouring ebay for a replacement unit? my gti has the 6 disk changer in the boot and thats been pretty reliable, so cant even swap them over as a test to rule out anything else being at fault.
