Bluetooth® Hub gives local control of your TOYOTA COMFORT+ system in your vehicle. Only smartphones supporting Bluetooth® Low Energy can communicate with the Bluetooth® Hub. Check your smartphone compatibility by downloading the app and select the option "New device". Note: OS support is subject to change without prior notice. COMFORT+ features: Turn engine and interior heater ON and OFF directly or by a timer. In timer mode, the system will automatically start pre-heating depending on the outside temperature or according to fixed pre-heating times. You can also monitor the outside temperature, the battery voltage of the vehicle and whether the 120V mains cable is connected or not. Bluetooth® Hub does not require a subscription. All products require installation of hardware in the vehicle. For more information see www.defa.com or ask your Toyota dealer.
