Garmin has released its Garmap software on memory cards, in either SD or MMC format. 

Customers will no longer have to activate the maps in their GPS units over the Web as the popular in-car navigation products will be supplied with Garmap maps-on-a-chip, giving then the benefit of immediate full use of the device.
Products that include the memory card-based map sets are the Street Pilot i3, Street Pilot 510 /550, IQ M4, N=FCvi 300/310/350/360 and Street Pilot 7200.
