MMC or SD Card Memory Card Installation

Your IntelliMap 640c uses a MultiMedia Card to store information, such as custom maps, waypoints, trails and other GPS data.

NOTE:

Throughout this manual, we will use the term MMC, but just re- member that your unit can use an MMC or SD card to store data.

Both of these solid-state flash memory devices are about the size of a postage stamp. An SD card is slightly thicker than an MMC. As this manual went to press, MMCs and SD cards were available in various storage capacities up to 2 gigabytes.

Additional MMC cards are available from LEI Extras, see ordering in- formation inside the back cover of this manual. MMCs and SD cards are also available at many camera and consumer electronics stores.

The MMC slot is located in a compartment on the front of the case. The compartment door is located at the lower right corner. The following figure shows a close-up with the door opened.
