Yeah, that thing pisses me off too. Know of no way to turn it off either. I don't mind if it just beeped once, but the damn thing beeps everytime it hits 37 degrees. On a drive up to SF one time, it beeped constantly. I drove up early in the morning and the damn temperature kept fluctuating btw 36, 37, and 38 degrees. Every 5 minutes it was "BEEP"!
