I have now added navigation to the system described in
post #1.
I went with the Alpine Blackbird
(Click Here) I thought it was the best choice for my application because with the Docking Unit I could put it under the passenger side seat. It is also the most reasonable price wise of the navigation units from Alpine. All controls and display are through the head unit in the Dash.
Features that I like:
-- Standard MMC/SD Memory Cards (Up to 4 GigBytes each) can be added with numerous MP3/WMA files for an endless music library. Files are up loaded via USB (or any standard SD card loader). It will play music back while navigating with voice prompts integrated into the system via the head unit.
-- The Blackbird includes a built in battery that is maintained while docked. Also allows the unit to be completely removed and used standalone.
-- Windshield mounting/docking station was included. I can remove the unit and move it to any other vehicle and use it.
I am very happy with this GPS receiver. The docking station antenna was mounted under the dash up front. No problem with reception (I've seen it track 10 satellites in the Garage w/door closed). I don't know what the sensitivity (dbm) is as the spec doesn't list it, but it is very good.
