Power your legend HCX, Summit HC, Venture HC or Vista HCX and save the batteries when in your vehicle. The adapter plugs into any standard 12-volt receptacle.
Purchased with the Garmin eTrex Vista HCx. Great thing to have when traveling down the road. I personally think the products made by company are the better choice even though you may spend a bit more up front.
Worked excellent! I know it's just a cable, so not much to go wrong, but you'd be surprised!
I'm new to GPS's so this could be the norm, but I like the way the cable completely cut out the battery, and then when you unplugged the cable, the GPS would warn me to either turn it back on, or it was going to shut off. In other words, it didn't automatically assume that I wanted to continue running on batteries. I like that I get to choose. I also liked that the GPS backlight stayed on while plugged in.
