Boombox GTS with WHIM

I ride a 2022 Street Glide ST with a BoomBox GTS and a WHIM. I use a Shoei GT Air II with a Sena SRL MESH system. I had to reconnect my Sena system to the bike and now the connection Fails. It does the same thing with other Sena Systems indicating the issue is with the Harley. 2 different Sena systems Fail connecting to 1Harley. Has anyone experienced something like this?

It's made by SENA under contract, and SENA made HD's comm gear until recently, so you'd think that generic SENA comms would play nice with the WHIM... it won't! You see, HD specified an AptX audio codec in their branded gear, while SENA uses an SBC audio codec in theirs. The AptX is better and more expensive, and while it's designed to fully support any SBC codec it finds, HD stuck in a software routine that switches to monaural if it doesn't see their AptX codec on the other end of the connection. So while SENA's branded gear "should" connect fine, well... The only way to get full control and stereo from older HDs is to ditch the WHIM and get a SENA FreeWire interface (requires HDs 7-pin accessory adapter). That allows you to get real stereo and full control functions, including CB (if you have the CB module & buttons installed). I was using the SENA 30S at the time. I also tested the Cardo PackTalk, which is another can of HD worms.
