i found this ipod interface made by USA Specs. its model number is PA11-GM45 and it claims to be compatible with 00-01 cadi deville. it says that once connected, you will be able to use the ipod through your radio using the cd changer radio and steering wheel controls. Does anyone know if it will work with an 02 stock nav radio. doesnt matter if you cant see the song info. as long as it is wired and i dont use an fm trans. ive been looking for something like this for a while....though i would prefer to see the song name etc...but at this point im desperate.
