The KTuner app is finicky on how it connects. I use the HAL9K ROM on the head unit and it works great on the version 3.0 and 3.05 updates. When I tried upgrading to any version above that, it does not connect. I have proved this to myself by numerous installs and re-installs of the ROM.

KTuner and the TunerView app work flawlessly together. Just pair it up in your bluetooth settings and configure it in tunerview.
