Since my OnStar navagation trial will still active for our drive from Murrells Inlet SC to Naples FL on Wednesday, I figured I'd leave the Garmin nuvi in the console storage and let OnStar do the navagation. One question though..... If it were just me and the dog, we could make the trip with two or even one pit stop. The wife will require 4 or 5. When we stop and turn the vehicle off, will the OnStar navagation continue upon continuing our drive without having to do anything? Or will I have to re-activate the navagation? I did have MapQuest send our destination to OnStar. Do I just start by saying the destination name I gave the location to OnStar?
