Similar to the GPS III Plus, the basemap on the GPS 12MAP will include cartography information for North and South America including a database of cities, interstates, lakes, rivers, railroads, coastlines, and exit information for the federal interstate highway system. Even more remarkable, the GPS 12MAP takes mapping one step further with an added CD-ROM capability. Simply insert one of Garmin's MapSource CD-ROMs into your PC, and download up to 1.44 MB of extra map detail into your GPS 12MAP.
The 12 parallel channel GPS 12MAP boasts the same physical characteristics as Garmin's 12CX (excluding color display), including a rugged, water resistant case, dedicated zoom keys for quick map scaling, and a high-resolution LCD display complete with backlighting. The unit gets up to 36 hours of battery life with four AA batteries and includes the ability to store up to 500 user waypoints.

- MapSource: Compatible with most GARMIN MapSource products. Accepts up to 1.44 megabytes of downloaded map detail.

- All device settings will be restored to their factory default configuration
- All user data (waypoints, routes, tracks) will be cleared from the device
- Satellite constellation data will be cleared from the device
- Press and hold the MENU button
- Power the device on while continuing to hold the MENU button
- Release the MENU button once the device has powered up completely
- Place the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite constellation data
- Occasionally, satellite data can become obsolete or corrupt preventing your device from acquiring a satellite lock.
- Performing an AutoLocate on your device removes all satellite data and allows it to re-establish a proper connection with the satellites.
- The steps below will walk you through this process.
- Turn the GPS off
- Press and hold the PAGE and POWER buttons simultaneously
- Release the buttons once the device powers on
- Place the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite constellation data
- TIP: Leaving the GPS device in a stationary position should reduce the time needed to locate satellites
- Added digit to False Northing component of the User Grid Setup.
- Corrected display of invalid characters.
- Added Differential Beacon Scanning.
- Added MGRS and Loran TD position formats.
- Corrected problem with displaying maps which are along the 180 degree longitude border.
- Modified the arrival alarm to give approach notification at intermediate route waypoints when set to 'On'.
- Only display copyright page when unit contains maps with non-Garmin copyrights.
