Hoi !

Please read my little post
here.
Google Maps works more or less perfectly with the Innov8. Positioning data is precise and exact.
But Google Maps itself could be a bit buggy, depending on the area displayed: I often experience a slight misalignment of aerial and street map views: Not exactly congruent.
This might be reason for the flaw you experienced as it indeed leads to a wrong position indication. But as said: This depends on the area displayed.
Another possible reason: System/GPS Data. Find the options for positioning methods. Make sure, INTERNAL GPS is activated ONLY. No web-assisted methods ! Otherwise, positioning might be unprecise. (You have to look for the exact path to this options yourself; I use a German menu and don't feel like rebooting after changing the display language.

)
The Innov8's GPS receiver is a quite good and precise one. It's more sensitive than many professional GPS receivers like Garmin 60CS and far superior to Nokia solutions.
I checked this; I don't just repeat fan boy statements.
