Yep, works great. It maybe a little slow in refresh, and if out of cell service, the topography may not load, but the trail and GPS will work. It'll prevent you from getting lost. Also, get a mount or your co-drive will have to hold it the whole time, which is a PITA.
But if you can drop coin, the radios we run are the biggest and best investment and super easy to install. With the installed high power radio, we can communicate and direct you pretty easy and avoid you from getting lost.
We can also program and help install if needed.
Fact. On the poker run I could hear everyone that had a real radio. All the handhelds came in as nothing but static.
