Upgrading The Audio/Navigation Unit Software
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
To carry out an audio/navigation unit software upgrade, the following steps must be taken:
CAUTION:
Do not remove voltage from the audio unit during the software update.
- Turn the ignition switch to the ON or ACC position.
- Turn the audio/navigation unit ON.
- Install a new navigation database CD.
- If the audio unit recognizes a revised level of software, it prompts 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 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.
