iPod Classic to Car Stereo

See doing a Reset of your iPod works, press select + menu keys until you see the apple logo

I also have a problem with my iPod Classic 160GB models. I have two, one old, one new. I just bought the new one to replace my old one, because the old one mysteriously stopped working with my car's connector plug. My son's and wife's (smaller) iPods and an iPod Touch both work just fine with it. The car stereo immediately recognizes it. At first, I just thought I might have damaged the pins, but after placing the brand spanking new one on the pigtail in the glovebox, it also does not get recognized by the car stereo, but the iPod Touch does. So obviously, it's not the car stereo that is the problem. The ONLY thing different between my 2 iPod Classic 160GBs and my other family members' iPods, other than size or model are that they aren't docked/synched at the main computer, but on a separate laptop computer. This only started happening in December. Anyone with ideas on possible solutions, please reply. I'm out another $250.00 apparently, unless I want to simply return the now needless new iPod Classic.

I am having a similar problem. My new iPod Classic 160GB will not work with my BMW ipod interface. Every other iPod I have owned or own works fine. I just checked my son's Nano and it also works. I bought the classic specifically for my car. Any idea why the classic does not work?
