Moved on to the next thing...
Not difficult at all. The hardest part was getting wire down the back end cap, but that wasn't that bad. Yes it is wireless. It came with my Garmin Rv GPS .
I've been wanting to get a new GPS (have a Rand McNally RVND 5510 that works good), but my old eyes have trouble reading the small print on that 5" screen.
However, I really want to get a louvered tailgate for my truck first, which is close to the same price as a new GPS unit would be.
