We finished the installation of my Z110BT yesterday. It was the first Evo X my installer had seen, so I was grateful I'd done some research ahead of time, and had brought my computer with me.

We had everything wired up and were programming the PAC unit when we hit a snag. When you pressed either the preset up or voice control button on the steering wheel, the head unit would power down, and the factory bluetooth prompts would chime in over the speakers. At least it was an indication that the MITO-02 was working...

In the end, we disconnected the wiring harness from the factory bluetooth controller box. This is located above the glove compartment in the dash... this thread illustrates it pretty well... https://www.evolutionm.net/forums/ev...evo-x-gsr.html

Hope this helps someone reduce the potential frustration of a new HU install.
