I can't seem to get the learning status of the Z1 into the "3D Hybrid" mode. After the sensor initialization, it only reads "Simple Hybrid". Also, my speed pulse does not seem to be registering any readings. Neither on the signal strength screen nor the 3D calibration screen. Could this mean my installer missed a connection?

Yes. Your installer failed to properly hook up the speed pulse wire to your avic.

Yep
