I have a question for you, I looked at your photo of your BG Micro Trimble GPS in your car.
You appear to have the Black side of the external antenna facing towards the windshield [and the GPS sats].

Is this the correct oritentation - the documentation didn't specify this that I read, so I figured the "black" bit was for mounting underneath the antenna, this the shiny side should face up, or does it not matter?

Does the GPS even work with the antenna upside down - or does it work, but "backwards" in direction mode, e.g. it reports lat/long correctly, but some directions are reversed left to right?
