The integration plans vary among the manufacturers. Ford will add audio input jacks that are iPod compatible to the majority of 2007 Ford, Lincoln and Mercury models. For an extra fee, the company will sell a system called TripTunes Advanced that will allow the iPod to be stored and charged inside the glove compartment. The driver can then use the iPod through radio controls or controls on the steering wheel.
General Motors has developed a device called the Personal Audio Link. The gadget allows synchronizing of iPods and the cars' XM Satellite Radio band so the XM interface can be used for controls (but a subscription to XM Satellite Radio will not be required for the device to work). The 2006 and 2007 Chevrolet HHR sport utility vehicles will be the first to get the Personal Audio Link.
Gradually GM will incorporate the device into the 56 of its new car and truck models sold in the U.S. The opt-in feature will retail for about $160 + installation fee. Mazda has not shown any specific details about the technology it will use for MP3 player integration. DaimlerChrysler's Jeep, Volkswagen, BMW and its Mini, and Honda Motor are examples of other car manufacturers who have already added iPod integration to some of their models.
iPods and other MP3 players have been blamed for several accidents caused by drivers' use of the devices while on the road.
