I thought I would save myself some bucks, but you know it seems more dificult than I may be able to do, so will see if Cadi dealer can fix it....
Cadillac Mechanic: JHoop, Cadillac Technician replied 9 years ago
There is no service information in any of my databases and I have 4. The labor time to replace the radio is a half hour so it can't be that difficult.
