Gopro Silver
I received the gopro silver for Christmas along with the suction cup for my Dashboard mount for my truck and for my Lincoln. I cleaned the dashboard in both vehicles and the suction cup would not work. I called the (888) number and that was no help. I will take the gopro back to Best Buy if I can't get it to work.
You do realize that it's not a "dashboard" mount right?
Dashboards have a bunch of small crevices (this is to help prevent cracking from the sun).
Those crevices make using a suction cup really hard.
Try mounting it to the window, I often mount mine behind the rear view mirror.
