Agree with the above. I have a fair amount of experience with traffic court- you did not get off because of your GPS; it was because of the officer's answers to your questions. Good job asking, though.
The #1 tip for any court situation like this is the question the officer about events on the day it happened. By default the officer's word (and/or his radar gun) is worth more than your own, but if you can get him to say ANYTHING that calls into question his recollection of events, then his credibility is reduced. Incidentally this is also why most cops take great notes.
