At what point will I need to purchase an external SD card to store maps onto?
A. Even though the iQue has a total of 32MB of internal memory, the Palm OS itself consumes about 10 MB of memory. This leaves about 22 MB of memory for mapping detail, additional programs, games, and pictures you may wish to store on the iQue. During your initial HotSync, this total is reduced to approximately 14 MB due to the installation of your basemap, voice guidance files, and other applications. There are several basemap options to choose from, and your selection will dictate where it must be stored?internally or on an SD/MMC card. Furthermore, the number of additional detailed maps you wish to have access to may dictate the necessity for an external memory card. Also, MP3 files (iQue 3600 only) must be stored on a SD/MMC card. SD/MMC cards may are found at most electronic retail outlets.
