  1. Could you give some directions on how to install ver 3.49 of the firmware? Thanks.


    • The easiest is to use the firmware upload feature in the Android configuration app. Install the Mobilinkd app from Google Play. Make sure the TNC is paired to the Android device. Then just download the firmware file from this site using your Android device. The app will detect the firmware and walk you through the firmware upload process.
