I bought the above unit from the UK, It is a option in Europe. It will not work with my cell phone option so I'm putting it up for sale. The unit works with all 2001 and 2002 C Class cars. Asking $375.00 including shipping. Comes in original box, MB part number A203 820 17 86. Works with steering wheel controls. This is a Mercedes Benz factory stereo unit. Will send picture of unit, if interested. Hooks up to existing wiring harness, no modifications required.
