Apple is working on a navigation system that will be used in the Mercedes Benz cars starting in 2009. Mercedes will have the exclusivity for 6 months and afterwards, any car manufacture could purchase the Apple navigation system.
In the last few yeas and starting this year with the iPhone as well, the iPod have had support from BMW and Mercedes and aftermarket car accessory makers. The iDrive system, as I have mentioned in a previous article, it is already supporting both the iPod and the iPhone and it offers complete control over them.
There are no details on whether the Apple navigation system will rely on Google Maps as a navigation aid.
