III) Mounting the phone
Mounting your phone is done by using a good windshield mount (i.e. sufficiently rigid, holding the phone correctly and correctly absorbing vibrations), and by positioning it correctly. No other type of mounting should be used!
The three rules that the phone must follow are:
- It must not move during the measurement (as little as possible in reality)
- It must be subjected to as little vibration as possible
- It must be aligned with the direction of movement of the vehicle and not tilted laterally, but can be tilted vertically between 0° and 90° in relation to the horizontal
The diagram below shows you the position the phone must have.

IMPORTANT: PerfectPower strongly recommends the use of one of the following two windshield mounts which perfectly meet all the required criteria:
1) WIXGEAR universal magnetic windshield mount (Amazon US)
2) T’NB universal windshield mount (Amazon France)
