You sometimes need to know the correct frequencies for your departure airport, waypoint airport, and destination airport. You need this information if:

You use the Air Traffic Control (ATC) feature but you do not use the Autotune feature. -or-

You use the Instrument Landing System (ILS) feature.

This article explains how to find the ILS and ATC radio frequency information for the airports.

Use one of the following methods, as appropriate to your situation.
