sd card?

[Not that Bob]

What does one gain by purchasing an sd card for a gps? All I can see is that the sd card has "maps." Doesn't the gps already have maps?

you dont gain anything anymore. Maybe when they first came out but most gps systems nowadays have built in memory. Only thing i can think of is if you travel to another country and that way you can change maps on the fly
