Specifications subject to change without notice.
1. Subject to accuracy degradation to 100m 2DRMS under the U.S. DoD-imposed
Selective Availability Program.
2. With optional GARMIN GBR 21 Beacon Receiver input.
3. The temperature rating for the eMap may exceed the usable range of some
batteries. Alkaline batteries can rupture at high temperatures. Alkaline batteries
lose a significant amount of their capacity as temperature decreases. If using the
eMap in below freezing temperatures, use lithium batteries for longer battery life.
4. Extensive use of backlighting will also significantly reduce battery life.
5. External power can only be applied using the GARMIN Vehicular Power Adapter or PC
Interface Cable with Vehicular Power Adapter with self-contained voltage regulation
