I have had absolutly no issues with the GPS on the AVIC-40BT..... I mounted the GPS antenae up in the passenger side pillar. It gets the GPS signal every time with in 10 seconds. So far every track I have been on around here has been on the GPS... Not sure why others think that the GPS is crap. I would rate it the oposite... I have a Garman zumo 660 for my motorcycle. I would rate the GPS as good as this unit.

Funny how some things work for some and not for others.....
