The radio and CD in my 02 GP GT works like a champ as far as the sound goes. The problem is the window that tells me what station I have the radio on or what time it is does not illuminate. Can the display window be repaired or replaced or is it all part of the radio unit? Is this something the dealer has to replace or can I take the unit out and send it off to be repaired or replaced and reinstall it without knowing some secret code? Thanks in advance, Bill
