thanks for the info edrock -- I will give it a try.

[quote]No, it does not need to be reprogrammed. However, if you already have the unit out you may as well perform the bluetooth update and use the newer phone interrupt wire mod method. Much cleaner and easier.[/quote] Could you please link me to the instructions to do this mod (phone interrupt) -- I read the directions for the TR7 and they seem pretty simple. Why do you say its easier and cleaner? Thanks for the info.

Does anyone know if the TR7 needs to be reprogrammed if the Avic Z1 is removed (as well as all the cabling) and it is transferred to another car? The TR7 was previously programmed and working, but I am wondering if I need to program it again or not to rehook up the unit. Thanks!!!
