Here's another trick I just figured out.
You can convert your coords to decimals here:

32.985472, -97.073528 and hit enter.
It will bring up the area, switch it to satellite and see it from the sky! Way Cool.
You shouldn't have to convert the coords to decimals in Google Maps or Google Earth. Just leave a space between the numbers.
Example: N 32 59 07.7 W 97 04 24.7
Your unit will also can display coords in decimals if you'd like. In the 'GPS Setup' menu select 'Coordinate System' and then 'Degrees'.
This is also useful when your buddy gives you a spot and you are creating a waypoint from an entered position. You can enter it in either format but you have to change the 'Coordinate System' first.
