Custom maps work only from the MMC card or SD card. When a card 

containing a Custom Map File is loaded into the unit, the unit auto-

matically loads the map into memory when the unit is turned on. 
Instructions for copying Custom Map Files to an MMC are contained in 

the instruction manual for your MMC card reader and Mapcreate soft-
ware. For instructions on inserting an MMC into the unit, see Sec. 2, 
Installation/Accessories.

GPS Data Files contain waypoints, routes, trails and event marker 

icons. Instructions for copying GPS Data Files between your computer 

and an MMC are contained in the instruction manual for your MMC 

card reader and Mapcreate software. 
GPS data automatically recorded in the unit's internal memory must 

be saved to the MMC (as a GPS Data File) in order to store it on your 

personal computer. GPS Data Files stored on an MMC must be copied 

from the card to the unit's internal memory before the unit can read
