CarPlay is not displaying all SiriusXM Channel

I just had an Alpine iLX-407 receiver installed in my vehicle. I have an iPhone 13 with Software version 15.6.1 installed. I have SiriusXM streaming service which provides all stations on my SiriusXM app on my phone. All the stations display and play on my phone when not connected to the receiver. When the iPhone is connected with a cable to the receiver, CarPlay recognizes the phone and will play SiriusXM music through the receiver. The problem being experienced is that CarPlay will not display all of the SiriusXM channels. Only a partial list of channels displays, and in a seemingly random order; not in the channels’ numerical order, not grouped by type of music. A station I might wish to listen to might not appear in the CarPlay display.

Is anyone else experiencing this issue? Is there a known root cause or solution? Thanks
