I have a used K40 Calibre Radar Detector that I paid $1049 to have installed 2 years ago. I had the unit removed from my Tacoma before I had to turn it in to Toyota. The kit comes with a front and rear sensor, LED lights for the dash, brain box, speaker, and remote control. Ebay has these listed anywhere from $450 to $800 for a new in the box unit. I am asking $250 shipped. The K40 detector was working with out anyproblems when it was removed. It has been sitting in a bag on a shelf in my garage. The only reason I didn't install this in my 4Runner was that it came with a Escort system in it.
