I have had this TND-750 for approx 6 months. The longer I try to use it the more I realize the mapping is about 3 years out of date. I have contacted Rand McNally about this very issue and they simply told me that is the most recent mapping they have. REALLY? Your Rand McNally! The map people! You cant update your maps? Also, it sent me down a non-truck route with a bridge overpass of 12 feet! This overpass has been there for 75+ years per the officer who gave me a $192 ticket! I wouldnt invest my $400 in it again. Nor any of their other products. Get over your bankruptcy and run your company Rand McNally! User's recommendation: Don’t waste your money.
