Well to make a long story short, I was out at my moto-x track today, and a freind of mine has a solo2 escort unit, not a bad unit at all, nice cordless unit for sure, he is quite an electonic guru himself. Well, we were tinkering and i showed him my laser which he thought was cool stuff. He then wanted to see if he could pick me up and if he was set up properly, well upon inspecting for laser reception his detector never went off not even to constant laser beam stream to the laser sensor of the solo? I immediatly knew something was wrong...my first thought was the detector must be messed up, so i attempted to use the v1, after my properly fuctioning well working v1 missing 2 legit laser alerts pointed directly at the laser sensor with nothing blocking it I became concerned!! Then the third time i shot it my v1 alerted but barley 1-2 inches from the laser sensor? I then pulled the detector out of that truck out side of the glass the detector worked miraculously....The thought then popped into my head something has change here what is making this do this? I then went over to my buddies drivers side window, and standing on a 45 degree angle to my dismay i noticed something about the windsheild it had some kind of a special coating on there. It seemed almost retroreflective for sure, almost serated mirror typed. If you stand from a 45 degree angle from a new 07 colorado you will see what i mean, it is as if it has a specail coating to eliminate laser passing through the windsheild!!! CHECK THIS OUT ALL COLORADO OWNERS BE FORWARNED!! Now some Colorado's i have noticed have this and some don't i don't understand why some do and some don't, but i know it is the case as i cheked out my local car dealer for sure directly afterwards. Before i got such a vehicle i would make GM replace my winsheild free of cost because this is Bull $hit!! I think everybody else on here needs to go check this out, and see what i mean you'll see one im sure if you look. It's totally a weird thing, make sure you look at it under light you can see the effect of blurriness alot better this way and the coating is a dead give away. Well hope everybody gets this message this is disturbing news for sure, especially since laser is already so hard to detect why do they need to make it any more of a prick?
