Using the sticker on the back of the Bluetooth beacon to adhere to your windshield is not a requirement, but is strongly recommended. We understand some local laws, vehicle sensors, or vehicle upgrades (e.g. tinting) may prevent you from mounting the beacon to the windshield behind your rearview mirror. If this is the case, choose another sturdy, stationary location to stick the beacon, making sure not to adhere it to a surface it may damage. Please understand the trip data captured may be incomplete if you choose not to mount the beacon at all. If the beacon is not adhered to a sturdy surface (e.g., stored in a glove box/console, fastened to a door, etc.), the accuracy of events can be impacted. Also, if there is metal between the beacon and the phone (e.g., if the beacon is inside a trunk or a metal-lined central console), the Bluetooth connection can be interrupted or weak, which impacts trip recording.
