Low Clearance Alert System for GPS
Low Clearance Alert System for installation on GPS. http://www.lowclearances.com/index.html I don't have experience with this system, but sounds like an alternative to spending $400+ for a new GPS ...

All that system does is use the highway departments info on overpasses etc. as a poi. You can get that info for free in RandMcNally truck maps./.....
Take it from someone that has compared the Rand truck atlas with the Low Clearance POI data base.
Rand is incomplete compared to the Low Clearance data base. Rand misses many (many) small side/county/city roads that long distance truckers never take.
I have the Low Clearance POI file on my GPS, it does work. What it does it alert you that you are within say 1/2 mile of the low clearance. What it doesn't tell you is if the low clearance is on the road you are on, or a near by road.
interesting. Did you have to add that POI to the GPS or did it come with it?
