C330 city names

I have a C330 and other than occasionally showing my maximum speed was
150mph (no way but no big deal), I really like the unit. However, I do wish
the maps would display city names. I often drive from Philly to South
Florida, and it would be nice to see which cities are nearby or enroute,
especially when I zoom out. Of course driving within a large city, this
isn't necessary, but during interstate driving it would be a nice feature.
Any way to get this adding memory and additional map software? Thanks.

Have you tried to e-mail Garmin tech support? They do answer.
