We recommend installation as described in the installation instructions. With the position specified there, you’ll have the best Bluetooth and GSM reception.
The Truma iNet Box should be installed at a location that is protected from moisture and wetness. Optimum sending and reception can be achieved if the Truma iNet Box is fixed as high as possible in the middle of the motor home or caravan. This could be in a cupboard, in the middle, with no shielding (metal) surfaces in the direct surroundings.
Choose an installation location where you can operate the Truma iNet Box at any time. This is because during operation, you may have to observe control lights or operate control elements, such as the pairing button.
