Is not true, because some forum and garmin said, with old serie gps, -----» not working with SDHC more 2gig, is not true.

Please note this limitation of incompatibility with SDHC cards only applies to certain models, not the nüvi 350! Nüvi 350 can read SDHC cards of 4 GB. Please read post #4 carefully.

I seriously doubt that, as the nüvi 350 is not capable of recognizing map files exceeding a 2 GB size. You don't need to take my word for it, you can read it for yourself here:

This information pretty much confirms what I wrote in post #4.

As established earlier, no map file larger than 2 GB will work on a nüvi 350, regardless of it being a topo map or a road map.
