No valuable instructions. The operating system is faulty. Not very user friendly apart from the actual programming. If you're looking for a button to cancel a route, you'll have to dig for 10 minutes to find it. It's not conveniently programmed. I don't need a GPS to tell me what clothes I'm wearing. I don't need GPS playing games. Yes, it plays music or movies. I need a GPS that works like a GPS. I need to find the accessibility of the buttons. Any guide would be better. Less BS from additional programs. It would be better if there were more really friendly activities with GPS. As for the GPS, I don't need to know which truck it's in. Not necessarily. There is no need to locate the GPS satellites that want to set the GPS. The clocks are always wrong by 1 hour and I advance them and they come back to the requested time. It's useless to find your time zone. I'm in PST and he still wants to be in Central Mountain. 1 hour difference. These are just some of the things that make absolutely no sense after a few basic resets of the device. Need an enema. Too much crap clogged it up. Now that I've spent several months with it, it keeps failing. I cannot set the time zone and have not done so since purchase. Unable to update since purchase. It made me get lost in a big city. The sticky system is not as user friendly as you might think. The size is good, it is a good size, but in general the use of this product or the chock. Don't waste your money damn sad even for a car it's not recommended. Some of the programs in it may be useful, but they are cheap, no name where the heck did you find these programs. Seriously, there are better truck mapping apps out there for your phone or anything that works or works on a phone or small tablet. As the old saying goes you get what you pay for you don't pay much you don't get much that's what i got i didn't get much i think my dog's nose is better than this gps
