DETROIT – Automakers are teaming up with Apple Computer to let drivers play iPods through their car stereo. This week, the 2006 Mercedes-Benz M class will offer a $300 integration kit that lets users control the iPod through buttons on the steering wheel.

In June, Volvo will begin offering an iPod connection in the arm rests of the S60, S80, V70 and XC70. Unlike the Mercedes system, which displays song title, artist and album, Volvo’s displays only track numbers. Pricing hasn’t been announced, CNET.Com reported.

Apple says it also has teamed with Nissan, Alfa Romeo and Ferrari to offer iPod capacity in 2005. BMW and its Mini brand began providing iPod connections last year. Owners of other music players, such as Sony?s Network Walkman or Dell’s Digital Jukebox, can buy devices from retailers that connect players to car stereos.

Until recently, most people who wanted to listen to an iPod through their car stereos had to rely on an FM modulator, which acts as a tiny FM radio transmitter, or an adapter that works only in cars with a cassette-tape player.

Now, several mobile-electronics makers, including Alpine Electronics, Audiovox, and Aamp of America, are offering iPod adapters that trick a car into thinking the iPod is a built-in CD changer, so drivers can use the radio controls to access the iPod. Most cost from $160 to $200, without installation.
