I still have an old ipod. So old it has no wireless ability. I want to use it in my car which doesn't have a cassette or cd player. It plugs into the car's usb port but the car radio "doesn't see it". Any tips on how to get it to work?
I think I can clear up your confusion.
By headphone jack there's a transmission of simple analog audio.
By USB however there are endless possibilities.
Ipods (and other apple devices) usually spoke a different protocol than simply providing file access as your car is likely expecting. On a pc you needed to install the application for that, too.
That's likely the reason for not working.
In this case it's easier to just stick in a mass storage usb stick with music files on it.
