SL55 AMG upgrade COMAND from 2.0 to NTG2.5 (2009 + harmon/kardon)

I found a thread detailing the upgrade on an R230 SL55 but can't seem to find it now. The upgrade is involved as the harmon/kardon system is entirely different from the Bose system and so you need new amps, harness, etc.

Anyone ever do this upgrade?
