I've used an old speedometer cable as a fish tool frequently. It's round, very flexible, but stiff enough to push its way past obstructions. Once you thread the tool up the driver's side A pillar, twist and push until the cable finds its way to the right location. Once its at the top of the pillar, use a piece of stiff wire with a hook bent into it through the sun visor hole to snag the end of the cable. Have fun!
