Compared to my Garmin 465t and 560 dezl this product is a dream come true, it has much more accurate maps, speed limits are by far more accurate, road restrictions are spot on, routing is a far sight better than either Garmin, and the truck services info (poi's) are accurate and easy to work with

I have sent in changes to routes, speed limits, and other stuff to be changed or updated through Rand McNally

It warns you clearly of upcoming sharp curves, or speed limit reductionsCons

You have to whatch speed limits it is not updated on all.but it will do evey thing I need and a lot more

It is not accurate in many aspects, does not know left from right, can't find many addresses, roads missing, and the speed limit is way out of date

Gives warning for speed limits

Amazing how it picks up a change in speed limit, mile markers, curves and low bridge areas

During your route there are warnings you can turn on/off, such as sharp curves & hills, how long you've driven, speed limit alert, state border alert, time zone change, weigh stations, toll booth alert, etc

When your about to come into a different speed limit.

The alerts are very highly specific to commercial applications that there is probably no way that driving workloads will lead you to miss anything that needs your attention, such as weigh station or border crossing or a change in max speed limit
