I have a Garmin GPSMAP 60C for sale. You can view the link below for all the details and features of this GPS unit. It is band new in the box (unopened), I purchased it only a few days ago so it will still have the manufacturers warranty for 1 year (it wasn't the one I wanted ). This is a great unit, they have mounts to put it on your bike, motorcycle, ATV, Motor home, Car, you name it. It has turn by turn navigation, and auto routing capabilities, color screen, etc.
Price: $350 ($450 MSRP)
