I like the traffic feature of my Garmin. I turn it on every morning on the way to work, and each night going home. I know the way now (been working there for 2 months) yet it is nice to have the traffic updates, mostly to tell me how long I will be sitting on the freeway. If it is to long, I will drive down a country highway, and take a back route. The Garmin will always update me, try to get me back on the freeway, but finally gives up and takes me to a small town, then straight north to my house.
Good luck,
Fred.
