These are nice units, I've got a 5900 installed in my ride right now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Only gripe is the 1 mile range is kind of ********. If your 1 mile away and it's a straight shot (and you can still SEE your car) then yeah it works, but if you get a couple hundred yards away, and put a building or two between you, you'll have to push it a few times for it to actually go through (if at all). But I've still had fairly good results, I can arm mine from inside my cubicle at work //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
