i recently am having issues with my avic-d3, i get a black screen, and the message says "there is some problem with the dvd drive", radio and xm still work but no map. also while driveing sometimes unit resets, similar to first starting the car. anyone ever seen something similar to my description? also for the record, my map discs are dual layered copies of the originals. please help, any info will be appriciated.
