This might be something to check, as it happened to me on a ride out last week, I accidently set my satnav to a random place, I had the prompt volume set to off so I didn't realise it was constantly telling me to turn, I have apple carplay so don't look at the satnav that often. I thought at first it was the 5G on my phone not getting a constant signal so the music was buffering. the only reason I found out was hours into the ride my do you want to search for fuel window popped up and when I said yes I couldn't here the prompt. then after getting fuel it asked if I want to resume my route.
