We’ve never been on the volunteer cheerleading squad for FM transmitters; in our experience, they’re downright useless in cities or other areas that actually have a large amount of radio stations nearby. But we’ll hand it to New Potato Technologies — this may be the slickest implementation yet. The newly announced TuneLink Auto looks like a typical cigarette adapter charger at first glance, but within, there’s technology that accepts audio over Bluetooth and then sends it out over FM. This prevents users from having to connect a dongle of any kind to their iPad, iPod touch or iPhone, but the built-in USB port is actually capable of charging all three should you choose. There’s even a 3.5mm output jack for channeling the tunes to a 3.5mm input on your head unit, and the (necessary) accompanying iDevice app should hit the App Store soon for absolutely nothing. The hardware itself is available now from New Potato for $99.99, and it’ll hit “select retail locations” in a fortnight or so for the same amount.

Never mind the extensive leaks, Panasonic, you’ve got a right to be proud about the HDC-SDT750. After crowing about its end-to-end 3D experience, Panasonic has finally made its HDC-SDT750 camcorder official, which looks like it will be the first of its kind to hit the market. Sure, this is just a baby step: the 3D mode is enabled by snapping on an included 3D conversion lens that splits the image in twain to be recorded as right and left images by the standard 1080p sensor. That means each side will only be 960 x 1080, so you can’t quite shoot Avatar in your backyard just yet, but it should look fine on standard 3D televisions. Unfortunately, you can’t do much more with the 3D video right now other than pump it out over HDMI straight from the camera — at least with the 3D stills that you can snap you can load them onto an SD card and play them off of AVCHD-compatible Blu-ray players. Still, these are exciting times to be alive, and you can always shoot in 2D with the no-doubt great 3MOS camcorder underneath (which seems to be very similar to the HDC-HS700) while you wait for the rest of the planet to catch up. The SDT750 will be out in October for a hefty $1,399 asking price. PR is after the break.
