Bluetooth Mic Volume - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 2007 with the Nav system. When using the hands free mic, people I'm calling complain that the volume is soft and a lot of background noise.

For other Toyota models I've read of ways to get into the adjustment mode on the system to turn up the sending volume on the mic.

Does anyone know how to do this on the 4Runner?

Thanks,

Pete

After the ignition switch is turned ON, check that the map is displayed before starting the diagnostic mode.

While pressing and holding the "INFO" switch, operate the parking light control switch: OFF | Turn ON | Turn OFF | Turn ON | Turn OFF | Turn ON | Turn OFF.

The diagnostic mode starts and the "System Check Mode" screen will be displayed. Press 'menu' and look for the Bluetooth button.
