800 NK Advanced Bluetooth

Even if i‘m enjoying my 800 NK advanced, i really don’t like the bluetooth that‘s built in. Maybe i‘m doing something wrong, but i use Carplay and an Intercom in my helmet. When my phone is connected to the intercom via BT, the sound is chrystal clear. No delay on Phone calls, etc. When i connect my helmet to the bike and use carplay, the sound is horrible, cracking and sounds like a trashcan 🫣 and when i am on the Phone, there is a 2-3 second delay of when the other person talked vs. when i hear it. Is the BT in the 800 NK advanced really that bad or is there any setting i need to change?

When my phone is connected to Intercom and bike but i select the output via intercom, all is perfect. Changed it to bile, horrible. So i assume it is the BT on the bike… how is yours? Any idea if this can be fixed?
