Backup Sensor Volume

[logan.d122]

I was wondering if the volume of the backup seneor on my 2002 Ford Explorer Limited could be increased. Sometimes I can't hear it, especially with the radio, a/c, and outisde noise. I read somewhere that a dealership could do it, but i don't wantto pay big $$$ for such a little adjustment. PLEASE HELP!!!

Thanks

i added the systems it afterwards, didn't know it was adjustable there was nothing on it that looked adjustable. With my '10's the factory radio mutes the volume but that seems to be a 4th gen thing.
