I had the old one (not sure of the model #) and it worked great and was SO user freindly. Then I bought the Sony GPS when it first came out last summer (again, can't remember the model #) and it sucked. I was surprised to find out how terrible the Sony unit was. I own / have owned many Sony electronics and I have nothing but good things to say. However, their navigation was a different story. I just bought the Nuvi 360 based on a friend's recommendation. I haven't had the chance to try it out yet, but I will probably do so later on this week.
