CONDITION:
Voice navigation prompts and feedback beeps are inoperative after starting the engine. This condition only occurs on Platinum grade vehicles.
RECOMMENDATIONS:
1: Turn ACC ON (brake pedal released, press start button, engine not running)
2: Allow headunit to boot up, once the home screen is showing feedback beeps should be working
3: The engine may now be started by depressing brake pedal and pushing start button.
4: Confirm the voice navigation and headunit feedback beeps operate.
Note: This will only allow voice navigation and feedback beeps to resume normal operation for the key cycle. After the key is turned off for approximately 5-10 minutes, the above process must be used again.
