New GARMIN GPS suggestions

do all the Garmins have the capability to recognize vehicle height?

Every GPS manufacturer has models which a person can input a vehicle height / set a minimum clearance height.

This is common in trucker and RV model GPS units, but not in general vehicle GPS units.

However, that is only a guide.

There is no way for a GPS unit to know about a low clearance bridge, overpass, etc - unless it is in the highway department database used to generate the map data.

Things like the POI Factory mentioned above have user submitted data to supplement the GPS database.

I am very careful about construction zones - because temporary overhead obstructions are all too common.
