What to do if there's no audio when using PowerConnect or FMDA with my Sirius XM Radio?

If you are not getting any audio when using PowerConnect or FMDA, verify that your Onyx Plus and your vehicle’s FM radio are tuned to the same FM channel. When using PowerConnect, make sure you are using the PowerConnect Vehicle Dock and PowerConnect Power Adapter. If you are using the Vehicle Dock that came with the Universal Xpress Car Kit, ensure that the FM Transmitter in Onyx Plus is turned On.
