From GPSur Dr. Erhard Regener:
GPS for Google Earth converts the free Google Earth version into to a real-time GPS navigation for laptop and netbook. The own GPS-position is shown and tracked in real time in "Google Earth". Also by night, with fog or mist you'll see your current movement like on a bright day on the screen. Each tour is automatically recorded. One may play animations of formerly recorded GPS logs.
I tried GPS for Google Earth 3.0 not GPS for Google Earth 220.127.116.11
Will not run on Windows 7 64 Bit. The cost of $32 is 1.5 times to cost on my GPS hardware (BT-359)
Could not test as it will not run on Windows 7 64 Bit. My bluetooth hardware Price = $ 24 Google Earth Price = Free GPS for Google Earth 3.0 Price = $32 The freeware Earth Bridge runs fine on Windows 7 64 bit
