Upgrading The Audio Unit Software
WARNING: This page is about a different car, the 2004 Lincoln Navigator and 2004 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
To carry out an audio unit software upgrade, the following steps must be taken:
- Turn the ignition switch to the ON or ACC position.
- Turn the audio unit ON.
- Install a new database CD.
- 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.
- 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.
CAUTION:
Do not remove power from the audio unit during the software update.
