I have a hitch mounted bike rack on my 2017 F60, and the back up parking proximity sensor is driving me nuts.

I've searched other threads and seems like there's not a practical way to disable the backup parking alarm via user settings.

Does anyone know where the backup sensor speaker is located? I'd like to disconnect that.

I could be totally wrong, but I believe that the sound comes out of the audio system's speakers.

Pretty sure there's no specific speaker, it is broadcast on all speakers. There's a way to control the volume of the proximity sensor beeps. If I remember it is in the main infotainment system settings.
