It took about 5 minuets to set this up to run with MS street and trip ( i am using 2006). it was so easy i thought there is something wrong. it has more features than i Knew, like Altitude( beside Latitude and longitude) gives you the speed that you are traveling( it matched the digital speedometer)also its very small. the only thing that i wish it had is to reconfigure the route if you miss an exit, it just says "off route" beside that its flawless.
