I have the z110bt which had updated to 120bt. I swear I had updated again to 130, but system says 2.0. But that aside for now

Anyhow recently I added in the hd module and while I was there connected in the nd-tmc10 traffic, which I delayed a few years in installing.. Thing is its not clear how to properly connect with the hd module. I tried connecting just to back of stereo, in line to big antenna, small antenna. But none seem to work. Also tuner seems to crash every 15 minutes in current config. Which is current between where the Y meets hd tuner.

Thoughts?
