I just purchased a AVIC-Z1 for my '04 Coupe that does not have factory Navi; it does has the Bose system. I am looking for some guidance regarding the following:

- how hard is it to install this system? I also purchased the Bluetooth, XM Traffic and iPod interfaces.

- for those of you that have these systems installed, where did you put the Nav antenna and the Sat antenna?

- I purchased the Scosche NN03 Wiring Harness, a PAC SWI-PS Steering Wheel Interface, the Double Din and a Antenna Adapter. Am I missing anything?

If I don't decide to take this on myself, can any of you recommend a good Audio Installer in the Southern California area ( I live in Chino Hills - Orange County, Inland Empire). Does anyone have a rough range what something like this would cost to have installed?

Thanks.
