yeah unless it has the updated stereo your out of luck
i know bavauto.com has kits for other models(only north american models

), but unless you can find a local supplier(speed shop/ performance shop near you), your best bet is to searh on ebay for generic kits, or for the upgraded radio
should run you about 120-150 can dollars(not sure in euro) for the generic kit, and around 300-500can for the radio
let us know where your from so we can give you a hand to find a reasonable location near you
