I have a 2024 CE04 that is paired with Schuberth C4 helmet with their SRC-System, and the helmet is paired with a Samsung phone. Everything works properly, i.e., I can listen to navigation instructions and music streaming off of my phone. I cannot, however, use the handlebar controller to adjust the volume of the devices. The only way to change the volume is to use the helmet mounted system and the buttons are hard to find with gloves on. Does anyone have a suggestion to get this to work properly? Did I not link something in the proper order or a setting on the phone not properly configured?
