Query: works great

This is my first time using a GPS and I found it easier then I thought it would be to use. There's a few things that could be improved with this GPS. Like using your own route when wanting to go your own way. And when I went through long tunnells like I did the unit turned itself off because it lost it's signal and I had to reset. But over all the unit performed great. And I will enjoy using this GPS in the future.
