The mounted computer in the truck has GPS tied to MS Streets and Trips (cheap version of MS Map Point). MS S&T Lets you import info from other MS Office programs (namely MS Excel), which is nice when you have hundreds or thousands of GPS locations to chart on the map.

I tried the road feature last night, and you are right..... Not so much.

I remember someone mentioning lithium batteries not working, and there is no option for lithium in the menu. Will they work with the unit set to Alkaline or NiMH?
