"great value. has all the useful features you would ever need."4.5 starson by kvshah
Pros: cheap and reliable. very easy to operate. i chose the 320 over 330 because i have 2 units. therfore i only have to buy 1update to cover both units.
Cons: very few times in chicago between tall buildings the signal would get lost. i think this is common to most gps devices.
Summary: i liked it so much , i bought a second unit.
garmin allows to update to the latest version if you buy the product after version release date. v7 came out just this summer. i think they release a new version every 2 years.
i prefer this over the i series because of the touch screen.
c320 + 2gb sd card is cheaper than the 330. i like the reliablity of flash drives more than hard drives.
