Just when you thought it was safe to go back into the water on Friday the 13th with your Bluetooth enabled iPod ... Belkin goes classy roman numeral with their TuneStage, which combines a bluetooth transmitter for your iPod with a receiver that hooks up to your stereo for wireless music transmission. The II features Bluetooth 2 for better battery life and lowered radio interference. Besides just interfacing with each other, the receiver portion can communicate with a PC or MP3 phone, while the transmitter can bump tunes from your iPod to bluetooth headphones (though there seems to be no AVRCP support for playback control with the headphones.)
The TuneCast 3 bumps up the staid nature of a standard FM transmitter with an LED display, memory presets, and 20-hour battery life.
