I have found that if I wait till everything is hooked up by Bluetooth, and only then hooking up the cable to the phone, that works best for me.
This worked for the iPhone.
Took my iPhone and my helmet out to my Spyder and turned the key on, rolled the throttle, and did not connect the iPhone to the USB cable in the glove box.
After a few seconds, the message about the iPhone being connected showed up. I navigated to the Bluetooth menu, and there it was! At that point, the iPhone was still not connected via cable.
Turned on the headset and waited, and... nothing.
The headset came with a very small set of instructions. 10 total pages, 2 pages for each of 5 different languages.
The only thing it says about pairing is that it will automatically enter Phone Pairing when you "initially turn on the headset". Which does not mean every time you turn on the headset, only the very first time you turn it on after buying it.
And if you dig into the downloadable version of the manual, the English version of which is 21 pages long, there's a pinhole on one of the speakers that you can poke to do a reset and start from scratch. So you can do a reset, and then turn it on again and pair it.
To turn the headset on or off, you hold down the + and - volume keys at the same time.
Turning it on plays a sound, turning off it says "Goodbye".
And, if you hold down the + and - keys for 5 seconds, THEN the headset goes into Bluetooth pairing mode. :banghead:
So my iPhone and helmet headset are now showing as Bluetooth paired to my Spyder, and my iPhone is also showing that it is paired to the headset. And after doing the pairing steps, and THEN plugging the phone into the USB cable in the glove box, the CarPlay icon is working again.
One of my favorite phrases from when I was still working as a computer consultant and was asked an obvious question, was RTFM.
Which of course means: Read The Fine Manual
