I have a navigation system and I'd like to know how is the satellite coverage in Hawaii. Anyone used Garmins there, how is the map coverage?(give a different answer) .
I've used Garmin and it's 100% coverage. Satellite coverage is good, but you'll keep losing the signal in the mountains and forests, so don't count too much on it in those places. Have an old fashioned map with you. I don't know much about other navigation systems.
