Not going to write a long review, even thought this unit deserves one. I've driven well over 1-mil miles and done most of my own routing so I pretty know whats the fastest and shortest. Have been using a basic garmin for the past three years and with ANY Gps unit they'll ALL get you in trouble if you let them. I was really excited about this unit, due to the size and the features. Allot of great grafics and on screen info thats usefull. But the most basic item that it was lacking was the gps tracking. I gave this unit allot of leadway on its mistakes due to the fact that it had allot of cool stuff that it did, but its ability to track you and route you was not even close to what the basic garmin could due. Its like the prossesor that they installed in the TND 700 was 10 years old. Example if I needed to make a simple route change I.E. in town down to the next street due to the fact that I couldn't make the turn or the street was blocked off, it would take the TND 700 upwards of 45 seconds to a minute and a half to reroute me. Here I'm sitting at a stop light waiting for directions and waiting that long with cars on my backside didn't make me happy. This is a problem that happened evertime you had to reroute, weather it was a simple street change or a major highway change. Also from the time you turned the unit on it would take twice as long to boot itself up. At least a dozen times with in a week it put me on the wrong roads and when I made a wrong turn it got it self lost....I.E. take left on xyz street, and it was some ones drive way. Or turn left in 800 yards and the turn was less than 10 feet away. You might think in a conjested city situation I might get a little mixed up, but this is out in the country. Twice it put me under 12'6" bridges when I'm 13'6". Of course I made sure all my truck setting where they were supposed to be. I also updated the OS version,via Rand McNally. All in all I expected alot out of this unit and got a unit that should of been field tested with some people that drive allot. It just had to many route mistakes. Going back to the basic garmin. This isn't just my complaints, I have three friends that bought the same unit and have the same complaints. All of us returned the units.
