Hi, I had a similar sounding problem when I first tried using my new patriot and crv. All seemed fine in my driveway, then started getting the A? (Don't remember the number) error about an hour into our 5 hr drive. Had to unplug it until I got home. Not a happy first time out with the toad experience.
I got a jump start battery to power it and have not had a problem since. My understanding is that the crv outlet doesn't provide sufficient power for the Patriot.
