You can use your Blue&Me-TomTom 2 navigation device to manage your hands-free calls. You should establish a Bluetooth connection between your phone and Blue&Me in your car, and not between your phone and the navigation device.
You can also use Blue&Me to handle hands-free phone calls without the navigation device. However, if the navigation device is in the dock and switched on, you can access all the functions through the navigation device, for example, answering incoming calls and calling POIs.
Note: For information about hands-free calling and Blue&Me in your car, see the Blue&Me user guide.
