Take of the cover to your speedometer, unscrew 3 screws. pull out the plastic cover. Lift the dash unit the hold your speedometer and odometer and underneath that is the speaker to it. I put a cotton ball and some tape over it and it muffled it to a nice boop boop, rather BEEP BEEP! So annoying but now I can withstand it without blowing some veins after hearing it go off and on due to my supid unsafe california passengers.
