Never had that, although I admit it was the first thing I ripped out mine within weeks of having the car as I hate the standard headunit, my main beef is the display, hard to read in the dark I found, anyway, I have a nice Sony one now which has been with me for 8 years and still going well.That did go through a phase of not liking some copies, but I found using Nero and TDK CR-R's worked for me.
Not Sure if thats of ANY
help!lol
