Drive Control: How to switch the radar/laser detector (for mobile speed cameras) ON?

To switch the radar/laser detector ON, you have to enter a code in the device's menu. The code consists of the 4 last digits of the serial number. Please check the bottom side of your device: there you can find a sticker with the serial number. Enter the last 4 digits in the Drive Control's menu, using the VOL+ and VOL- key. Press the red button to confirm the digits. Once all 4 digits are confirmed, the radar/laser detector will be switched ON. If not, you will receive the error message 'SN Fail'. Please try again if this occurs.
