I have a new Neotec 3 with the Sena SRL3. I link it with my Iphone 13 and Garmin Zumo XT. I then ride out with a friend using Group Mesh. For the first 5 rides with me guiding the Mesh has worked faultlessly. However last night I encountered an issue. Intermittently I could hear a load click and if my friend was talking the volume reduced so much that I could not hear him. Then I would hear another click and the full volume would return. My friend could hear me clearly all the time. I suspected that the drop in sound could be linked to an announcement or message from the Sat Nav, so I powered it off. This solved the issue. However this was never an issue before and I need to Sat Nav for directions. I can confirm that nothing changed on the Sat Nav setting or firmware. Does anyone recognise what this could be and how to stop it happening again?
