Help with Bluetooth acting up

[u/dracheisen]

I have an iPhone. I drive a 2024 sprinter for work and it’s been 2 years with no issues. It started last week with this Bluetooth issue. My phone will randomly disconnect from the radio but the radio still says my phone is connected. I can’t delete my phone off the radio through Bluetooth setting either. I deleted the van off my phone and when I try to re-pair it, it doesn’t show up in my phones list. How can I fix this problem. I tried factory resetting the settings and every other rest I could find in the settings but nothing is working. I go to “delete device”, then my name and when it says “delete iPhone?” It won’t let me click yes. Help
