iDrive via IP? - BMW uses Internet Protocol underhood

There's a variety of flavors of in-car networking standards that corral the large number of embedded computers and nodes present in the modern automobile. BMW Research and Technology, an R&D division of BMW, has found Internet Protocol up to the tasks that the other standards currently perform. BMW engineers used a standard PC and connected it up to the expected gear -- ECUs, engine and chassis control systems, even a multimedia server for the entertainment system. The reasoning behind using IP versus the more specialized protocols is to anticipate future needs and requirements, as well as reducing costs. Costs drop because fewer specialized components are needed, and the new version of IPv6 is even better than the more than fine performance from IPv4. It's a little spooky to think that your fly-by-wire throttle could be trying to chat with the engine using the same technology that we use to send instant messages, but IP proved itself capable enough even for critical safety functions. The research is ongoing, but BMW's work bodes well for adding functionality and decreasing costs. Adding aftermarket goodies should be fairly painless and service shops will also have an easier time of it by going with a more universal language. Imagine surfing the web with iDrive, though. Blech.

In-dash nav systems do damage to resale value

How's this - you pay a nearly ten percent premium to get a factory navigation system in your new whatever, and when it's replacement time, that very same nav system will cost you again, whacking 1% off the car's resale price. It makes perfect sense if you try to use some of the integrated nav setups in one- or two-year old used cars out there. Not only did they cost a fortune, they're not always terribly user friendly, and honestly, how often do most drivers need a nav system? Some at Autoblog love them in our review vehicles, but going the same route every day makes it virtually impossible to get lost. For people who travel a lot to areas they've never scouted, there's value in nav, but when you can get an aftermarket unit for far less, integrated nav starts to take on a pallid appearance.

Automakers are starting to get hip to this fact. Hyundai, while they're offering integrated nav on the Veracruz, sees no problem selling Garmin aftermarket units right off the showroom floor. The portables are a fast growing segment as consumers realize the value of third-party, portable nav systems. Portable navs are less expensive, offer features that cost a lot more on factory systems, and are upgraded far more regularly. For $1,000, you can get a system that offers real time traffic and weather data, works with bluetooth phones, and can be even more functional with the addition of optional software cards.

Not only are the aftermarket units cheaper, they're portable, so you can use them in whatever car you please. Of course, luxury buyers being who they are, there's a certain need to show off that a factory navigation system fulills, but puffery is costly. The quick path to obsolescence that all in-car electronics take means that very in short order, you've got an expensive, unfriendly, limited hunk of LCD-interfaced crap in your dash.
