Ok so clearly no one has fitted an Intravee yet.

I decided to locate the Alpine KCA-420i in the compartment at the front of the trunk and I ran the cables through to the backseat, under the cushsion and under the carpet to the central console. I located the actual Intravee inside the centre console connecting tge CD changer and IBUS links and feeding the IPOD connection through a hole into the storage bin. Biggest challenge is routing the cables under the carpet along the tunnel between the backseat and the centre console.
