Looks like a good one there.
Just a bit of info for those who have not owned one yet:
Lifetime Maps means that you will be able to download and install updated maps 4 times a year (unless that interval has changed).
This is important because roads are sometimes changed, new highways built, and new points of interest (like gas stations and restaurants) become entered into the database. If you don't have lifetime free updates you have to PAY for each update as the unit gets older. If your map database is 2 years old and it costs sometimes $79 for one update, you probably won't pay it...you'll just put that money to a new unit and so it's even MORE expensive.
You do need to have a LOT of bandwidth during a map update...it's about 2 gb for one update. And you have to register the unit online and use a laptop or desktop computer with a good solid internet connection to do this. Cell data is NOT the way to do it...it's normally too unstable to depend on for a 1 or 2 hour download. But two or three times a year, find a good solid, and fast, wifi connection with no data caps and it will work well.
Lifetime Traffic means that the unit has a special car adapter cord that has a receiver built in, and it will show traffic congestion on the screen, and will beep about 2-5 miles ahead of the problem, to alert you. This only works in larger cities, on major highways, and it will not work at all in small towns, or out on the open highway.
If you only pass thru large cities occasionally, you probably don't need Traffic. If you live and drive in a larger city, its worth it.
