I have a 2003 G 35 and the radio and cd haven't worked for years. They told me it was some sort of a board and at that time would cost thousands just for the part. Now, I don't have any temperature controls, which happen to be on this same board as the radio, and every now and then the compass and temp. area just above the manual clock start flashing, but temp up and down or fan up and down do NOT work when it is flashing.

Does anyone know the cost of these boards now? I am assuming that the radio and temperature controls are all on this board?
thanks
