"ditto" on the Garmin..I have 4 Garmins..one marine for my boat and 2 more with 4.3" screens..the most recent is the 5" screen 1450LMT.....lifetime maps and traffic.....the lifetime maps are worth $60 to $100 by themself......I got this one because I wanted a larger screen....I love it and thought I got a good deal at Sams for $250...then saw an add yesterday for $179.....a terrific buy.....don't remember where I saw it.....just google it.....it shows you the posted speed limit and your speed....if you exceed the posted limit your speed changes color......it will tell you how long to get to your destination.......I don't like the Magellans...
