Mercedes-Benz new myCOMAND system has appeared at the Los Angeles Auto Show, taking on the fourth-generation BMW iDrive. Whereas the latter has an Xbox 360 feeling, this one gets some clues from Apple's, specially Coverflow and the menu navigation, which reminds me of the first version of the Apple TV and Front Row. One big difference is that myCOMAND is connected to the web, grabbing information wirelessly and presenting it through their own on-screen apps. Looking at the high resolution screens and the feature list, it looks very good:

• Off-board navigation: The GPS is constantly updated, from the maps to the points of interests. It also has a satellite overview and the search language is open: you can write directions without having to follow a format. It looks like the are plugging into Google Maps for this one, although I'm not sure how well the writing will work using their navigation knob.

• Trip assist: This part is quite nice, grabbing information pertaining your planned trip from different web sources and presenting it in a useful manner. You can, for example, see the weather forecast for the trip, as well as giving you the possibility to make hotel and restaurants reservations from the system itself.

• World radio: Instead of using a normal radio, this one plugs into the web to access all the stations available. The menu gives the possibility to access radio via genre. More interesting is the idea of storing your music in a web server and accessing it through the system directly, without the need to connect an digital music player or storing things locally.

• Internet telephony: It has support for voice over IP systems like Skype.

• Web browser: They also include a web browser, in case you need to get more information than the one provided with the thin clients above.

• YouTube: For huh... hmmm. Some reason.

The navigation knob, which looks similar to the Powermate, is simpler than the iDrive 4.0. We will have to try it to see if their user interface approach is better or not. [Mercedes Benz]

Atomic Floyd is new to the personal audio headphones game, and their first bit of kit is actually pretty decent looking. The AirJax headphones are in-ear, but have earloops made of something they're calling Titanium2 (even better than version1?). They're also made of "acoustic steel" which is apparently specially heat-treated for maxiumum audio quality, and you can rotate the in-ear part relative to the metal frame for a custom fit. The AirJax gets a UK launch first in December for $180, putting them at the luxury end of things. [LuxuryLaunches]

When we first wrote about this comically huge Walgreens LED sign — the largest of its kind in the world — construction was just getting under way. That was May, and now they're done. D3 LED, the firm behind the sign, finally turned on this 17,000 square foot, 340ft tall, three-sided tribute to technical and commercial excess — and what timing! But before we start challenging the rationale behind displaying 300ft moving Tampax ads, it's worth looking at the extraordinary tech inside this thing.

The display, which wraps around the three most visible sides of 1 Times Square, is capable of playing contiguous video using all of its surfaces at once. Made up of a mix of 13 60in plasma TVs and over 12 million individual LEDs arranged in diagonal panels, the screen is purported to display a resolution of "20 times the resolution of standard HDTV," though it's not completely clear what that's supposed to mean. As far as the back-end goes, to play just 30 seconds of video calls for 150GB of data sent from 30 computers, all of which, I hope, one day conspire to make the greatest BSOD of all time. The sign was flipped on officially last night, though the trial run, featuring the awesome test pattern picture in this article, took place on Wednesday. Check out the local news report below for some more background and neat little renderings to put the whole thing into perspective. [NYT, image from Gothamist]

Sagem Orga, in partnership with BlueSky is targeting the array of cellphones (and presumably mobile-internet enabled PCs and such) that currently don't have GPS with this new invention: a SIM card with AGPS aboard. Clever stuff indeed, packing all the chips for a "highly accurate GPS receiver", wiring and antenna into a thumbnail-sized space. We've got to wonder how good its satellite fixes will be with such a small device though, and since it looks like every gadget that comes out has GPS aboard nowadays, adding GPS to a device via its SIM card might just be a temporary stopgap option. But it'll undeniably have lots of applications when it hits the market. [BGR]

We've written about the sci-fi sounding Army's Future Combat System before, but the Army's just demonstrated a successful test of one of its components: the Quick Kill vehicle defense system. Check it out: the Raytheon system uses an electronically-scanned radar array to detect an incoming anti-tank rocket-propelled grenade, then vertically launches a countermeasure missile that blows the round to smithereens in mid-flight, saving the RPG's intended target. It's a very simple test setup, and, of course the real system will have to deal with complications like vehicles in motion, but it's an important first step. And it goes boom. [Danger Room]
