Software Update Instructions
1. Open the hood and connect a battery charger to the vehicle.

3. Insert the key and turn the ignition to the "ON" position, but do not start the engine.
Turn all accessories off. TURN THE RADIO ON (Figure 1).
4. Press the upper left "OPEN/CLOSE" button on the radio (Figure 1).
5. Insert the correct update disc, as determined in Step 2 of this procedure, into the radio.
6. Compare the CURRENT RADIO SOFTWARE number with the UPDATE CD

CAUTION:
ONCE THE UPDATE HAS BEGUN, LEAVE THE IGNITION IN THE ON POSITION AND DO NOT TOUCH THE RADIO!
8. Several different screens will appear during the update process which may take about 5-12 minutes. Once the update is complete, the radio will return to the normal user screens. Wait for the radio to re-read the disc and display one of the 2 screens shown (Figures 2 and 3).
NOTE:
Figure 2 will be displayed on vehicles with a non-navigation radio. Figure 3 will be displayed on vehicles with a navigation radio.
9. The current radio software number will now match the update CD software number. Select "No" on the radio screen face to return the radio to the normal user screens.
