I picked up the Navigon 2100 on Sun. at Office Depot. They couldn't tell me how to get the free lifetime traffic subscription so I went to Staples, price matched the Office Depot ad, and picked up another unit with the free lifetime traffic included in the box. There is a sticker on the front upper right hand corner that refers to it. When you look inside the box there is a card with the redemption code. It took me about 5 mins to set everything up with the free traffic. I returned the other unit to Office Depot and I am very happy with it's performance.
It tracks both freeways and major streets in your area. It will list any traffic reports on the freeway both on the map and on a separate traffic report screen. Large city streets are displayed with colors only on the 3D map to represent traffic flows.
