which one is the best ?

Its a toss up between magellan and garmin

Also I heard the Navteq maps are better

Best one would be the one that meets your needs and then some. (And at the best price).

Had the Garmin C320, returned it. Got a Mio 310x and a Nuvi 350. Of the 3, Nuvi 350 best. Mio 310x was good and seem to have more features than the 350. But didn't like the routes it selected compared to 350.

Both have their advantages and Disadvantages but when you take Customer Support into Consideration, the Garmin comes out on top 1000% (maybe a bit more)

I am not saying Garmin's is perfect but it is far superior to Magellan's.

I have had to use both, and I cringe at the even the thought of ever calling Magellan again.

I have worked with NavTeq on their data side and seen pretty good quality data compared to others in the market. Also Navteq puts efforts to correct/update their existing data on quarterly basis.

Their data for San Juan is way out of date, their data for PONCE is sketchy and often wrong-one way streets, etc (I live in NY and have a vaca house in San Juan

Thank you all.
