I have the UNIKA fitted with a Mki 9200 in Corsa D. I have not used (about 20 minutes) but then for longer UNIKA for Mki long. Cables for BUS control I have already attached home on the adapter cable (accessory). However, the Unika did not run. Everything was as advertised and actually she had to work. But what was not in the manual and only through the support via email (very good support) was explained is that after installation first on the steering wheel buttons "before" back "," before "," back ". Then go. Cool, the Information would have saved me about 4 hours Nagut care, but:. Every keystroke makes not only what at the LCI but also original radio Wow so if I hear ne CD and rumtippe in the telephone device menu, then is always a song before or just. switched back. This brings with it a lot .... woow very comfortable ...
