Belkin's milking its TuneBase product line for all it's worth, today introducing two new wares that are just marginally different than those we've seen before. The new TuneBase FM and TuneBase Direct both enable iPhone users pick up a call handsfree (via the built-in speakerphone) as well as channel tunes to one's stereo via an auxiliary input jack (that's the 'Direct') or FM transmitter (and that's the 'FM'). The TuneBase FM is set to hit shelves next month in the US for $89.99, while the TuneBase Direct should make its way out this month for $69.99.

Update: iLounge has a quick hands-on with the TuneBase Direct if you're into that sort of thing. And we know you are.
