Prox. sensor worth it?

I have a 2002 avalanche. It has 30% tint on the front and limo tint on the back (I hear tint is a problem). Will a prox. sensor protect both in and outside the truck? All I really want it for is warn-away. Also would it protect the bed of my truck? If I were to get one it would be a dei 508d. Any comments would be great! Thanks, DyerDyer

I have a 508D in my jeep cherokee center console to protect my car pc lcd screen, but I don't know if the 508D is all that great.  It seems to work as it should 80% of the time, but then the sensitivity setting seems to drift around the other 20% of the time.  I think the alarm feature is awesome because you can leave your windows rolled down on hot days, but the warn away feature is questionable.  The warn away chirps on my 790XV aren't all that scary, especially since people barely pay attention to fully blaring car alarms these days.  I actually think the warning chirps might be bad, drawing more attention to you car, letting car thieves know something good is inside or arrousing a bunch of bored teenagers.

I have the 508D for my truck. I think it works great and I also have tint on all my windows. The way I have the 508D set is for a person to see what I have they would have to cup there hands around the window to see in. The 508D will do warn away chirp if someone where to try that.

thanks those are some good points Dyer
