Unstable Pairing with HTC One New Install

[NebraskaMarine]

I received my Bluestar II module yesterday, and installed it in my 2008 Hummer H3 Alpha. It paired without issue, but would switch between "Radio" and "Phone" on the stereo when making a call.

I read a little bit on the forums here, and thought that I'd flash the firmware, remove the pairing on my phone and re-pair everything once back in the truck.

All of the above was completed. The phone and unit re-paired quickly and easily but the symptoms remain the same. When making a call, the Bluestar II unit will switch from "Radio" to "Phone" on the stock stereo, and will loose connection completely after a minute or 2.

Any help would be much appreciated. I will be sending the unit back and sharing my experience with others if I can't get it working very soon.
