*edit* heck with it, I'm just going to convert it to DC power. It'll make life a lot easier I think. I know this has been covered, but after a few weeks of searching and reading threads my eyes are going crossed and I'm no closer to finding what I want. It might not even exist. I want to mount a GPS on my XR650R, which currently has AC only power. I have a 200 watt stator, running a 100 watt headlight, brake lights, and turn signals. Probably a bit of room left but not much. Is there a GPS that can take AC input, is water resistant, can handle being on a XR in trails, and has maps loaded? A trail Tech Voyager almost meets that description, but it doesn't have maps. Huge bonus points if the unit can be swapped between bikes easily, and isn't in the $500+ range. Needs- - AC power compatable - Durable - Loaded maps - Able to load routes, or waypoints, or however you guys do that. Never tried it before. Highly wanted- - Water proof. I have a cheap on my FJR, but if it starts raining I need to put it away. - Switchable between bikes. I would like to be able to use it on the XR and the FJR mainly, but I will probably put a mount on everything I own. - Something with hour meter or odometer or something. Not really needed but would be nice to have. - Speed shown. I guess on the XR and haven't been arrested yet, must be doing something right. - Works with an Apple Computer. I could use my dad's computer if I had to, but I'd rather be able to do everything here. Bonus points- - If I can save my route, then load it into my computer and start naming roads. I would love to be able to have road maps of my local riding areas. Most of them are a maze of trails going everywhere, and mapping them would be sweet I think. - Reasonably priced. I'm not spending a grand unless it washes the bike for me too.:loll I'm guessing that the GPS I just described doesn't exist. If I need to I might just bite the bullet and put DC power on my bike. I just didn't want any added complexity, every part I put on is one more part that can break IMO.
