A shop installed pac-swips on the z110BT but my bluetooth and VR did not work on my Mazda 3 2010 steering wheel controls. It cannot be program. It is version 1.6.8 and they tried two modules with 1.6.8, no luck. Everytime a tech tried to program the BT function, it just shuts off. Shop told me they will order more 1.6.8 and try again next week. Do you guys think the PAC is defective or is there a different way to program depends on car models/make ?
What buttons on the steering wheel were they trying to use for the VR? Not all of the buttons share the same CANbus wires, so it made need a second SWI-PS. If it's buttons for factory bluetooth, then they probably communicate with the bluetooth module, and not the radio.
