IPod Integration

[Muttley]

I have just had my CDC replaced under warranty. The unit the dealer put in is older that the original one! I was hoping to get the latest version that plays Mp3. At least I have an alternative to just the radio. I have decided to use my IPod Video but am totally confused as to which is the best method to integrate. I have got it down to 2. The recently introduced Ipod unit from BMW and the Dension Icelink. Can some one please give me their thoughts/observations. The BMW Ipod unit is around £195 plus 1.5 hours fitting. I am not sure exactly what I need from Dension - Ice>link plus and Gateway 300? I have Nav and no DSP.

Thanks
