I have the Magellan TRX7 that has bunches of preload trails. It is Android based, so Clunky compared to Mac stuff, but does work. They keep updating software and it is getting better. You can download additional maps too. It will record your path, so can back track to truck. One hint though, shut off unit to wipe screen (don't ask, just assume correct LOL). I have had mine a while plus had the Yamaha Adventure pro version when had my YXZ. Having Yamaha team up with them was best thing to happen to it. Be sure to look at the waterproof versions (they have cheaper versions that aren't)
