My daily driver is currently an '11 e90 335i coupe. I'm having an issue with my USB slot and Bluetooth connection. My phone finds my BMW on the Bluetooth list but it won't let me play any music because the option for Bluetooth is greyed out on my car. When I plug in my iPhone it doesn't read it or any USB cable for that matter. I tried cleaning out the USB slot. I'm guessing I'll need to replace it! Does anyone know how much this will cost if I diy? And if so, has anyone else had this problem ? Thanks !!
