I bought myself a GX 470 for my birthday in June and I LOVE it. Only 32k miles on it and in like new condition. My one head scratcher is that the seatbelt chime is off in this vehicle, and I move way to fast for my own good and sometimes forget to buckle up. I'd like to turn the chime back on and see if it drives me crazy. I found instructions for turning the belt chime "off" elsewhere on the Lexus Forum site and figured that would get me into the menu I need, but those instructions don't seem to work for the '05 GX 470 at all. I never get to the alleged "b-off" "b-on" menu. Can anyone help me out here?

As far as I know, the 05 GX does not have a seatbelt chime.

I don't think my 08 GX has one either!
