I have read the many post to disable the reverse beeping - however, I’m wondering if there’s a way to change it from constant beeping when in reverse to one beep on a 2006 (I don’t have scanguage, but do have an odbii)
I doubt it, but if you buy a mini-VCI that comes with Toyota Techstream software you might find a way... I've disabled my reverse beep in the past, but once that's done I've on more than one occasion backed up a little after going over the limit line a little at a red light and without the beeping I've stepped on the gas to go forward and quickly hit the brakes because I realize I'm still in reverse. The beep is a hassle, but it does serve a purpose. I've never accidentally floored it in reverse when I thought I was in drive when that constant beeping is harassing me!
