First, check the available space on your device because it might be full. If that’s the case, please delete some of your old data to make room for new tracking data. If storage space isn’t the issue, make sure the orientation of the unit is conductive to the best connectivity of the unit: 1) If inside the vehicle, lights (Flashback) or “This side up” text (Tracking Key) should face the sky. 2) If the unit is being placed in a position under the vehicle, follow the opposite of #1. 3) No trunks, or engine compartments.
