Have you changed the head unit anytime recently?

Also the iphone may not be compatible with your setup. Im sure everyone will tell you it works on my bmw yada yada yada but the software revision in the car can make a big difference on how it handles the bluetooth module on the bus. So either the car may need update flashing or there may be a phone upgrade to get around it.

they did replace the head unit about a month ago.

I have been using my Razr for the past two years no problem. i think i have the 9th Gen bluetooth module ...

do i need to upgrade to the 12th gen mondule?

I honestly dont know enough about the bluetooth module to give an opinion on that since my car doesnt have it. Theres a ton of tsb's on the bluetooth but not the iphone since its newer than my newest tsb info.
