Problem with the use of a change in Google Maps (map does not appear). The latest version of the site automatically suggested by the software does not correct the problem. It took contact support in the US (via email) that quickly sent me an update link arranged everything. [...] The features look good (monitoring speed, altitude according to time or distance and path delay in Google maps or Google earth). Running Windows 7 without worry. I have yet to see where to put the case for GPS reception is always ok.
