Belkin today unveiled a pair of updated TuneBases built with the iPhone in mind. Both the TuneBase Direct and TuneBase FM route audio from Apple devices to the car stereo while simultaneously charging them over the 12-volt port and cradling them on a flexible neck that puts the iPhone at a more viewable position. Users only have to tap a button on the TuneBase itself to take or end the call in speakerphone mode and can use either model for listening to music.

A special design should support using most iPhone cases with exposed Dock Connector and headphone ports.

The two differ only in their choice of audio transmission. The lower-cost TuneBase Direct at $70 uses a 3.5mm port to provide a wired connection to the aux-in jack on those cars that have the feature. The TuneBase FM at $80 routes through a free FM channel and auto-scans to find the frequency with the least interference.

In the US, Belkin anticipates the TuneBase Direct shipping first with an in-store window of early June. TuneBase FM models ship in mid-July.
