Just had the z1 installed however i need some custom faceplate work done ( too embarrassed to post pics right now ). Had an installer rough it in.
Installed the z1, BT, XM/traffic nav, ipod, RV Camera.
FYI, I was worried the ipod would have poor performance, but it is working fine, search is fast ( against my 4gig Nano ). Really happy with it.
The BT calling ( with my Sprint 700p ) works fully functional ( transfer all contacts in one swoop ), but caller hears an echo. I don't hear any echo.
Car: Porsche 911 Carrera 4 Cab. almost exactly as mivey.
