Specifi cations are 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. External power can only be applied using the GARMIN Vehicular 
 Power Adapter or Travel Charger. Modifi cation to these or other 
applications will void the product warranty.
4. Both Talk Time and Standby Time are dependent upon the operat- 
 ing characteristics of each Network System and will vary from 
 system to system.
 The maximum talk time is given for the GSM band at minimum 
 transmit power: Level 19 - 5 dbm. Talk time will be reduced 
 at higher power levels. At Power Level 8, for example, talk time is 
 estimated at 4 hours. 
 The maximum standby time is given for the GSM band with 
 the NavTalk “Power Save” mode enabled (a partial display mode), 
 service indicator Off, and DRX 9. With “Power Save” mode 
 disabled, service indicator On, and DRX 5, standby time is 
 estimated at 150 hours.
 Extensive use of backlighting and/or the GPS Receiver will also 
 signifi cantly increase power consumption.
