So I'm attempting to install a remote start that I purchased from Mypushcart. I got my 2005 Lx470 2 years ago, and it came with this random knob that not even the previous owner knows what it was for. There are also these LED lights near the speedometer. I tried turning the knob once, and the lights will blink, and this annoying low-pitch-chirping sound started to play. Would anyone have an idea as to what this is?
