Upgrading The Audio/Navigation Unit Software

UPGRADING THE AUDIO/NAVIGATION UNIT SOFTWARE

To carry out an audio/navigation unit software upgrade, the following steps must be taken:

1. CAUTION: Do not remove voltage from the audio unit during the software update.

Turn the ignition switch to the ON or ACC position.

2. Turn the audio/navigation unit on.
3. Install a new navigation database CD.
4. If the audio unit recognizes a revised level of software, it prompts the user to confirm whether or not they would like to carry out a software upgrade. When the Updating System Software screen is displayed, press the YES button on the display screen to accept the software update.
5. The audio unit carries out a unit reset, upgrades the software and carries out a second unit reset upon completion. When the audio unit returns to normal mode, the software upgrade is complete.
