My Nuvi 1450 has always shown my home location about 100 to 150 feet down the street no matter what solution was tried. It has been reset, good signal, most recent updates. I just replaced the 1450 with a 2797 which shows the correct home location out of the box. have a nuvi 1450 lmt that I want to use in a vehicle with a 6 volt system. I'll need to use the Garmin for 8-10 hours at a time which will exceed its 3 hour battery life.
