I have an 18, the XT, Sema 20S-Evo and a Samsung Galaxy A51. Riding buddy with an 08 also has the XT.
For my riding buddy, I bought a Bluetooth dongle from Amazon
Amazon.com: GOTECK Mini Bluetooth Receiver/Car Kit, Portable Wireless Bluetooth Car & Hands-Free Adapter 3.5mm Stereo Output (Bluetooth 5.0, Built-in Microphone) for Home/Car Audio Music Streaming Stereo System: Car Electronics
Bought a USB powerbank for $5 at local 5-Below. Linked to his XT and plugged it into his aux input in left pocket. Works for him and he still has his CB. Occasionally it does unsync, restart one or the other to resync.
For me I have sena linked to XT by pressing the link button on sena. Have no idea what position it filled. Sena previously linked to bike, phone fully linked to bike. Phone linked to XT for music, but usually use the USB.
I occasionally lose sync with bike or XT on the sena. Usually resyncs itself after a bit of time, or I'll power down and restart sena to resync. Occasionally turn XT off/on to resync it. When listening to the USB music, the XT directions will override and be heard. CB overrides everything and can be heard.
Anyhow, if you're expecting 100% connection and working, don't think it will happen. Overall it works, could be better and the minor issues are small in the big picture.
