Query: Excellent out-of-box functionality, but..

I bought the Quest 2 after researching all the Garmin products, plus the products from Magellan and Dell (Dell's PDA/GPS is not going to be continued).I was literally able to open the box and set up the unit on battery power. The maps are pre-loaded, so finding locations is a matter of setting state, city, and address. Everything has worked, mostly..The but part..the documentation is not as complete as I'd like it, and some things, like how to charge the internal battery (or if it can be charged), are nonexistant.I mapped a trip to my folks in Arkansas, and it did a lot of recalculating when I knew the shortest route and it didn't. And it had their house on the wrong side of the road.Locally, it had me turning onto streets that didn't exist.I will look for map updates (and hope they exist) in the future. I'm a month into ownership, and so far, I'm impressed.
