"Bright, large display and easy storage after removal."3.0 starson by tbrd113
Pros: Large screen, ease of storage and bright screen.
Cons: Can't learn your driving preference, Doesn't always take the best route.
Summary: I first purchased the Nuvi 350. After never owning a GPS system before, I thought that the 350 was fantastic, but had a small screen. I really wanted the bigger screen, so I returned the 350 for the 660 since it hgad the traffic receiver built in. After reading all the negative reviews, I was hesitant on buying the 660, but I did it anyway. I like the wide screen, the brightness and traffic receiver. I didn't need the Bluetooth since I have "hands free" built into my Charger. I really think the Nuvi 350 was more accurate. I wish there were more personalized screen for trip preferences. Shortest route or fastest route doesn't mean the best route. I came down the NJ Turnpike and it kept telling me to go through Trenton, NJ instead of taking me on the PA Turnpike. I just learned to ignore and the 660 would eventually recalculate. I prefer major interstate highway and prefer to avoid local roads while traveling long distance. I believe the maps are about two years out of date too. I didn't need the traffic receiver which put about 150.00 on the price tag. If the simple Nuvi 350 was available in wide screen and less money without the traffic receiver, I would have bought that.
