First of all I have a 2006 G35 sedan with the non bose HU. I am installing a avic z2 with bluetooth, sirius, steering wheel controlls adapter, and motion bypass. I am needing to know where is a good place to mount the navigation antenna? Also where can I find a list of the wires that I need to find in the car like the "vehicle motion wire" or something like that? I am not a newbie to installs as I always do my own but it is usually on a different car every time and it is always something new to learn. I plan on doing a full write up with pics on every last detail of the install for the forum. I know that there are a lot of people who get on sites like this and just milk for info and never return anything. I am not one of those people. I like to contribute, here is proof that I am doing this...

 

I mount my antenna on the right corner under the windshield. Vss wire is in the plug that has 5 wires on it. That is also the plug you will need to install you steering wheel controller (i think...). Sorry its been awhile.

 

I dont know about sedans, but coupes have a 'hidden' area for the factory gps antenna. It is located behind the clock if I am not mistaken. You can do a search on here for it.

I hate the look of the gps antenna on the dash.

 

I will not put it on the dash, thats for sure but I do want it to get good signal.
