Upgrading The Audio Unit Software

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

1. Turn the ignition switch to the ON or ACC position.
2. Turn the audio unit ON.
3. Install a new database CD.
4. If the audio unit recognizes a revised level of software, it will prompt the user to confirm whether 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.
CAUTION: Do not remove power from the audio unit during the software update.
5. The audio unit will carry out a unit reset, upgrade the software and carry out a second unit reset upon completion. When the audio unit returns to normal mode, the software upgrade is complete.
