Only the beginning: hard drives in cars

There's already been a silent technology explosion in automobiles over the last ten years. Command and control has become largely a computerized affair. With high and low speed data buses throughout the automobile, your car is basically a network. It used to be that you'd press the power window switch and current would flow to a motor, or it would trigger a relay. It was simple to execute in the design and manufacturing stages, and troubleshooting was a matter of time spent with a test light and a meter. Modern cars use protocols like CAN, or Controller Area Network, to facilitate the liberal smattering of increased functionality we all desire in our vehicles. Press that same window switch now, and a message is sent to the central processor that you desire a change in the window status. The central processor then alerts the window motor to energize in the proper direction, and then it's off to the races for the glass. Sounds overly complex at first blush, doesn't it?

The old way had some drawbacks that the new systems hopefully alleviate. Firstly, there were lots of potential failure points with analog control systems. Also, components had to be wired to each other for functionality, and that required lots of wire. Wire is expensive (checked the price of copper lately?), and it adds weight and takes up space. Networking protocols allow automakers to integrate functions as never before - check out the way the MazdaSpeed 3 dials down its power output depending on steering angle - while using less wire and having a system that's more reliable. These changes have gone on virtually unknown to most motorists, but the cool stuff is just around the bend.

Chrysler first to offer Sirius Backseat TV in 2008 models

Chrysler announced today that it will nab another exclusive for its upcoming redesigned 2008 Chrysler Town and Country and Dodge Grand Caravan minivans. In addition to their popular Stow 'n Go and Swivel 'n Go options, the new soccer mom-mobiles will be the first available with Sirius Backseat TV. This extremely handy technology beams three channels of kid friendly programming right into your minivan. Video can be displayed on either both flip down screens in the back, or also the third screen embedded in the dash if the vehicle is parked. Mom and Dad can also choose to listen to Sirius audio programming up front while Dick and Jane rot their brains on cartoons in the back.

The channels being offered are particularly appropriate for children, just the type of people that often frequent the back seats of minivans. Nickelodeon, Disney Channel and the Cartoon Network will all be beamed and received via two small roof-mounted antenna. We're particularly pleased the Cartoon Network was thrown in there, and hope to all hell that Adult Swim comes in.

What's more, this technology will only cost $470 as an option, which includes the first year of service. Considering that it's the first of its kind on the market, we think the price is reasonable. Although, by this time you've likely checked off the box for the MyGIG entertainment system, which costs a heady $1,700 on some vehicles. We imagine that money is of little concern when trying to mute the little ones, and Chrysler comes through again with an exclusive feature for its new minivans. The Sirius Backseat TV function will also concurrently be offered on the 2008 Chrysler 300, Dodge Charger, Dodge Magnum, Jeep Commander and Jeep Grand Cherokee, though it makes the most sense in these vans.
