We all know that mounting your suction cup on a textured dashboard is pointless as it won't stay fixed, but sometimes it would be very useful.
In my case I don't want a permanent fix since I need to use it in many different trucks, so I use one of these:

The "Cup Buddies" are ideal!! They come in different sizes, and the new transparent ones stick very well to the suction cup, so that if you take the mount off of the dashboard, the disc stays on the suction cup rather than coming of. The mount stays put all day long, very reliable! Make sure to clean the dash surface first... I use it for the Mobius mount, as well as for the phone mount. I love them!
My favourit tripod dash mount?

It's small, low profile, sturdy, has an adjustible ball mounted joint, and VERY easy to mount, just push down and you're done! I bought it on Ebay, but I can't find it there anymore.
Also I have considered this one from Akron:

If you need a magnetic mount:

You may need a ball joint to adjust the camera's recording field of view. Nevertheless, a nice thing to have when needed......
