I currently have a z2 installed in my 2006 f150. The unit also includes, bluetooth, backup camera, steering wheel controls, mic, xm, and ipod connection. In order to replace the z2 with f90bt(nothing wrong with z2, just gonna put in diff vehicle) how much stuff from the z2 can be reused with f90bt? i mean can i keep the steering wheel controls, backup camera etc same or will they be replaced too or need different wiring? I can open the dash and take the z2 out myself but thats all i know, is it as simple as just taking the wires from z2 and hooking it to the back of f90bt? Please let me know thanks
