I am trying to update the software and I realized this unit was never registered in order to update it. Yet when I try to register it, this model doesn't come up so the system doesn't recognize the serial number. Any suggested would be greatly appreciated.
Don't ask why , so far the updates are provided without incurring additional expense . Download the files , unzip and save to a new folder on your desktop . http://www.auteltech.com/TPMS%20Diagnostic%20&%20Service%20Tool/403.jhtml
