If your TTU-720 seems to be failing, before returning it to Synovia, first try the following troubleshooting steps to make sure that something else other than the hardware isn't causing the problem:


  1. Make sure that the vehicle has a clear view of the sky.
     
  2. Make sure that you have removed the activation magnet. Wait a few minutes after removing it for the device to report to Synovia.
     
  3. If you have a backup battery pack, try replacing the battery. Wait a few minutes after inserting it for the device to report to Synovia.
     
  4. Verify that the TTU-720 is reporting to Synovia:
     
    • On a mobile device, in the vehicle list, tap your vehicle name. If the TTU (trailer tracking unit) is reporting live, a map will appear showing your vehicle’s location. Below the map, check the number to the right of Sats (the GPS satellite count); make sure that the number is 8 or higher.
       
    • On a computer, check to see if any events are being reported for the vehicle and that it appears in its current location on the map.
       
  5. Try swapping out the nonfunctioning TTU for a known working TTU.


If you've tried all these troubleshooting steps and the device is still malfunctioning, follow the RMA (return merchandise authorization) procedure in Returning Hardware and Obtaining a Replacement (Performing an RMA) to return it and obtain a replacement.
