Thanks Mark!
I suppose I'm due for a few minor updates here...
As for the Jenko, certainly for the money you can't beat it. That setup is only in the vehicle for special occasions & big trips. It is simple to pop in and out. I have the base plate permanently mounted to the tunnel. No special hardware used, except for the additional brace I added. I still get a bit of vibration, but it is less than what movement comes from the computer screen itself.
I say give it a shot! As before, for the money you can't beat it. Lately I've been dreaming about a different system. I think it would be incredibly cool and efficient to remove the radio and permanently mount a small tablet PC in the center of the dash!
