Once the arm rest slides back, two buttons are visible. One is the Parking Sensor on/off button, my other "button" is a dummy blank one. where can i find one to replace it with to use with something else.

 

excellent question

 

That's where the rear window shade button should be.

 

correct, i have that button in my gs350. not anything fancy

 

Thank you..anyone happen to know part number or where I could find one?

 

Think I found it for $68! Guess I'll go with a regular button for now..and replace the blank plate later...lol...working on a little project...

 

Install a blank button and put a NOS logo on it. Or an eject seat toggle from the old James Bond movie.

 

Lol...
long story short....we had a little boy few months back and this is my daily driver.... had a mirror strapped to the headrest...couldn't stand the way it looked... So got rid of it and replaced with a tiny camera mounted under headrest and a small ..screen up front...button to be used to turn it on and off

 

Had it set up with out a button, having to plug in and unplug the power everytime.... Finnaly got around to finishing it.... Thought I'd share some pics of it finished since I mentioned it...
