loaded GPS
Loaded with lots of information. Would be easier to use if touch screen. Marine lake detail did not include my favorite lake which is the second largest in its State (44,000 acres). Bummed since I could not find a list of the covered Lakes at the Garmin site.

Garmin GPS
The unit arrived in good order. Am still working on the operating manual. This GPS has many options to set up and different ways to connect to a vehicle. It will take some time to take advantage of all it has to offer.
