Belkin has posted information about a new car holder called the TuneDok. This is the same iPod holder as being sold in the VW iPod connectivity kit for the ‘Pods Unite’ promotion. The TuneDok features ‘AirGrip’ technology (suction cup) for secure placement, a large and small rubber base plus adapter cup for exact fit in a cup holder, cable management system, and comes with a 3 year warranty. The TuneDok fits all iPod models and retails for $29.99, but is not yet available. Update: The TuneDoc is expected to ship September 15.
