Awesome system, bought it for my g35, put it on for a few months, then got rid of my car and it has been sitting in my garage ever since. Great system, practically invisible, comes with a remote which is little and discreet, great to turn it off whenever you need to. Anybody that knows K40 knows that they are very expensive, I'm willing to let my go for $300 shipped or trade for an iPhone 3gs or iPhone 4 (+ cash from me). That is a great price, I'm selling it so cheap because I'm leaving the country for a year and want to get rid of it before I go. You can check it out on

it is the the calibre DL-P. great system, invisible.
it also comes with a K40 defuser, laser protection system, great tool, it saved me a few times, once I was able to slow down from goin 85 to 70 before they got a good read on me.

I can't upload pics as attachments so I'm putting them in thru photobucket.












The remote

 

the readout display is just a few LEDs? how old is the system, warranty remaining?

 

yes you only have the LED's, it's about 2yrs old, no warranty

 

 

how hard was this install?

just paid a laser ticket haha...

 

Well I had a mechanic friend do it for me in a few hours for a case of beer . You do have to take off the bumper since the antiradar goes inside of it, but the laser defuser is easy, you just mount the license plate bracket on and you are done.
