Congrats on the new ZR and welcome to the discussion!
Better get some pics up soonest, or you'll be hounded ruthlessly...
Afraid I can't help on the aftermarket GPS & Bluetooth -- I got mine with both. Personally, I've got Garmin's in my other vehicles, I like their ability to navi using lat & long -- haven't figured out how to do that with the Nissan Navi...
Again, congrats on the new Roadster and welcome to a great forum.
