Apple working on a GPS unit?

It wouldn't be Sunday on the Mac web without a little wacky rumor to keep us interested. A German magazine by the name of Focus has a brief item today claiming that Apple is working on a GPS unit for cars. The article goes on to say that these units would be available exclusively for Mercedes during their the first 6 months of existence and then spread to other car manufacturers.

Will an Apple branded GPS unit be coming to your car in 2009? I'm going to go ahead and say this isn't very likely. It would be more likely that iPhone 2.0 has built in GPS and some sort of car mount. That's a rumor I could get behind (though to be clear I have no inside information about any of this).

Thanks to everyone who sent this in.
