I need to mount the gps antena on this vechile could I put in on the side or back glass. thanks Ken

You can try it, but if the tinting on those windows contains metal (most good tint does) then it'll cause a pretty severe degredation of the reception. If you don't want to put it on the outside of the car, why not put it near one of the speaker grilles in the dash.

I concur. Put it on the dash, center or either corner should be good enough

P.S. Use the little magnetic pad

I would probably just put it on the dash like others said.

but if that is stock tint in the back like it appears to be then its probabl not metallic on that application since most gm metallic tint apears very silver/mirror like.

I have a 2002 Blazer and I put my gps antenna under the dash. I just stuck the magnetic plate upside down under the dash and then stuck the gps antenna to that. I get a good signal there and it's hidden.

Here is my post on my install.
