You had the H series TCU in your vehicle and swapped the K series in. You could leave the H-series and have the 4G connection. The firmware in the H-series is the latest (or close).
This unit will not talk to your vehicle as is. It will need a firmware downgrade and asbuilt will need to be modified for you vehicle. What is the issue with leaving the original H-series unit?
