How to remove adhesive pad from windshield ?

I just installed windshield mount for my GPS unit but decided to remove it. However, I can't remove adhesive pad. How can I remove it?How to remove adhesive pad from windshield ?
I have had good results using wd-40 and a plastic ';razor'; style blade, available at most auto parts stores auto paint supplies stores and even Wal-Mart.


Soak the pad with wd-40, allow several minutes to penetrate, then use the plastic blade to peel off the pad.





Sometimes the application of heat(hair dryer) can loosen the adhesive enough that the plastic blade can remove the pad.





WARNING! Do NOT use any sort of metal device. I t WILL scratch your windshield. Plastic blades only!How to remove adhesive pad from windshield ?
wd 40 would work but then you may not be able to use the pad. I'd try using a screw driver or razor blade, prying off what you can of the pad leaving some adhesive and then using wed 40 or rubbing alcohol to get off the rest. A auto body shop would be able to get it off with ease.. and probably for free. I'd suggest going there because if you screw it up then your dash and your gps wont be the same
The old school razor blades (one edge and the other side is folded metal so you can hold it) are good to scrape most of it off. Then you need a solvent to dissolve the glue. Goof-off is a product sold at hardware stores and home centers that is handy for that kind of thing. You can get the old blades there too.
Use WD-40 to get it off; it will remove it.
Soak the area in windex, then gently scrape it off with a razor blade. Works for anything sticky on glass.
use a razor blade and scrape it off very carefully
did you try using a single edge razor blade?
