Hi I would like to know if I have mistakenly turned off the beeping of my reverse parking sensor in my camry 2013 It used to beep when I would put the gear in reverse, but now its quite even when I reverse or am near to an object, do I need to take it to the dealers or there is some sort of button that I might have pressed with which it has gone silent, no work done on the car and nothing is wrong with the car and it has just stopped by its own, no accident or sort of mishap that would have stopped it. thanks Saj
