Keith, since you seem to be THE Garmin c330 guy ... how much memory is built inside? I found that I couldn't put ALL of the North America data in the unit last night, and had to select the "West" region, dropping all the East Coast big cities. Did like that I could dump the East Coast into an SD chip. A 4Gig chip worked fine, leaving 99% unused, which makes me think that the internal memory of the 330 is darn small. Do you know the actual number?
