Default practical lubricity

The car holder for my GPS navigation system uses a ball-and-socket joint. It
holds the unit without any slipping -- but no matter how much I fuss with
it, I can never get it into exactly the position I want. There's simply too
much friction, both static and moving.

I've tried silicone spray lube, but it doesn't do much good. I've thought of
lithium grease, but... Nah.

Any suggestions?

Thanks in advance.
