Jeppesen's Garmin 430 is an avionics GPS autopilot navigation system. Periodically updates are made to the data. To enjoy optimized performance from the Garmin 430, you must update your system to receive these updates. The manufacturer advises that third-party memory cards do not work with the Garmin 430, so users must purchase them directly from Jeppensen. A USB adapter must be purchased as well. Find a link to the company's retail page in Resources.

Download the Update Manager program. The program places an icon to your desktop during installation.
