I have an 03 ESV with factory nav/ bose radio. I bought a touch screen unit to upgrade PN 10377531 GMT800 TNR. The radio and unit are supposed to be a plug and play compatibale with my XM radio and CD changer. Well, everything works but the XM radio and CD changer. Am I not connecting something?? or is this unti not compatable with my XM and CD changer as stated?? :thepan:,:bonkers:
