If we duplicate that with an external battery pack with a mini USB output it should do the same, I'll hasten to add that I am not an electronics guru, nor do I want to fry the GPS. There's no harm in getting an external battery pack and trying it out
if I can use my Car GPS then I can save $650 for the Edge800... in any case I'll check out the Scosche product as well. Thanks
The adapter has a female to male MINI USB 90 degree angle. Both are mini including the female part of the adapter. And yes, the car power cord with the male mini USB that plugs into the back only provides power but the USB to mini cord provides data transfer AND power. With the little adapter it allows you to plug the GPS into a USB source and power the unit without it going into data transfer mode and allowing you to charge or power it directly. I don't use my computer with the GPS very often and I haven't updated the maps since mine didn't come with a lifetime update package. I also haven't managed waypoints for a long long time either. If this Garmin model 1300 had programable routes, I would be hooking it up to my computer all the time and downloading routes/GPS cordinates off of the web.
