iPhone 12 Bluetooth car audio right speaker only

Hi,

My iPhone 12 has recently been playing audio on the right side only in two of my vehicles. But works on both sides and is normal when I use wireless earbuds.

The balance is centered under the accessibility setting category and the mono setting is turned off. I’ve turned the phone on and off. I’ve also removed the device on both the vehicle and phone then reconnected.

One vehicle uses Ford sync and the other vehicle uses Chevrolet my link. Same issue with both vehicles. Audio is on the right side and I have checked the balance on both vehicles and it is centered.

Not sure what else to try. Thank you!
