So at the moment I have the dreadful Ford 6000CD unit, in my Mk2.5 Focus. However, I have heard that some OEM Sony stereos contain USB functionality.
How easy is it to replace the original stereo with a Sony unit, and use the USB functionality?
Is there like a USB port on the back of the unit, which can simply be extended with a cable?
Or will it require a much more complicated install, with the need to modify lots of wiring looms?
