I just got a Magellan 1412 for Christmas. I was wondering if I should be so bold as to modify the factory navigation dock to make it fit the Magellan, or if I should swap it for a Garmin piece. I saw a bunch of threads on it, but none that actually modify the housing. Also, is there a way to hardwire it to the truck? I would much rather use a hardline instead of utilizing one of my 12volt outlets.
