For the Nearest Repeater function to work, the GPS must be enabled. The ID-31A supports the use of either the internal GPS or user supplied external GPS.

By default, neither GPS is selected. To enable the internal GPS:

• MENU - GPS - GPS Set - GPS Select - Internal GPS

You may also want to set the Power Saving for the GPS

• MENU - GPS - GPS Set - GPS Select - Power Save  - Auto

It may take a few minutes to acquire a valid signal. You should locate the radio so that it has a clear view of the sky. Once acquired, you can view the current information by choosing

• QUICK MENU - GPS Information

Once the signal has been acquired, you can now see the closest repeater

• Press and Hold the DR button for 1 sec. - Select FROM field - Select Center Blue Button - Near Repeater
