Belkin has upgraded their TuneBase lineup to handle hands-free calling in addition to pumping your iPhone music wirelessly to your car stereo.

Both the TuneBase FM and TuneBase direct offer push-button call pickup and a speaker phone, but the former also includes Belkin’s ClearScan technology which automatically finds the best frequency at the push of a button. The FM and Direct will run $US90 and $US70 when they are released in early July and June respectively. [Belkin]
