We have a Garmin and really like it. You can purchase a lifetime upgrade that allows up to 4 upgrades per year. However, we still carry a road atlas and check it against the GPS as they do not always have the best routing or the very latest changes that may have occurred.

With Garmin, it depends on the type of system you buy as to what different maps you have or can install. There are foot maps available for some models and some even have truck information such as weight limits and low height clearance warnings. As with anything, the more options you want, the higher you need to go in models and price. Good luck with your search.
