How to connect ZÜMO XT2 and 2 intercoms XCOM3 (Sena50S)

[Cuadrados]

Hello everyone.

I'm writing here to see if anyone can help me, because I don't know what else to do now, and I don't know if my problem is with the GPS ZUMO Garmin XT2 or with the NEXX XCOM3 (Basic) intercom, since I don't know which device is failing.

I have two NEXX XCOM3 intercoms (I think it's equivalent to a SENA 50S), a ZUMO XT2 and my motorcycle is a BMW 850GS Adventure 2023. I have been able to connect them together, so I can talk to my wife, but when I connect it to the GPS, I can't hear the GPS instructions and it disconnects. If I use the intercom alone with the GPS, I can hear the GPS instructions, but I can't do it if I connect my intercom to the GPS and my wife's intercom at the same time.

How should I make the connection diagram, the connection order and what channels should I use on my intercom and my wife's so that I can listen to my wife and the GPS at the same time without any signal dropouts?

Thank you very much!

First remove all pairing in XT and both headsets.
pair rider headset to XT2 ( as GPS )
pair you phone to the xt2
pair pillion head to riders headset.
Do not connect headset to the phone

I am anxious to hear how you make out and hope that your experience is better than mine with Cardo Packtalk Bold headsets and an XT. The problem is that the spoken navigation from the XT mutes intercom communication and then is very slow to release it. The conversations interruptions became unbearable, especially considering that my wife doesn't know when she has been interrupted by the XT. I now ride with spoken navigation turned off when my wife is onboard.

I spent a lot of time seeking a solution but no joy. Connecting both headsets to the XT seemed to work except that the connection to one of them was always dropped after a few minutes. The XT didn't seem capable of maintaining a connection to both headsets. Cardo has an audio priority setting about which their manuals says "When audio priority is set to Intercom, you cannot hear navigation app or SMS messages from your phone
during an ongoing intercom call." but this does appear to apply to a connected satnav.

If you pair the Sena as second phone with the zumo then the priority is differnent.
