I did a bit of experimentation and found a GPS hardware mod that helps with reception, accuracy, and fix time. Fitting a better antenna than stock means better GPS performance. Here's some before and after pics to give an idea of the difference. In practice it means I don't worry about GPS fix any more... I just drive and it's got a fix by the time I go looking for directions...
Any yes, the car was in the same place for the test (my driveway). The after pic has a more accurate position.
PM me and I can hook you up with one (or lots...).
BTW, the screen protectors were part of another trial to find the best option for antiglare, antireflection, contrast, etc.
