my d3 doesn't seem to know where i am (whenever i try to view the map, it thinks i'm stationary in california....only problem is i'm in texas!). i don't know if i accidentally pressed something or what. any ideas on how to fix this?

Did it ever work, or is this a new problem? Have you tried hitting the reset while you are out in the open where it gets satellite reception?

yeah it has worked since i had it installed....until recently. and where do i find the reset button?

There's a small pin sized button on the top left of the face.

You'll need something small like a pen or something to push it.
