Greetings, I recently bought a blue-tooth adaptor for my CL500. The car does not have a phone installed, but it's pre-wired.
From the bits here and there I gather that it's a 15-minute deal to install it (part number B6-7-87-5855).

1. Would anyone happen to have instructions on how to install it into 2004 CL-class?
2. Does anything else have to be configured (like command DVD unit)? I have recently had the latest software upgrade on the command DVD unit.
3. I am techically inclined, should I try it myself, or should I just take it to the dealership for installation? (The reason I am asking is that I bought it through a friend who has a discount there, and it would be a bit odd to show up at the service department with a unit in a box).

Thank you kindly for your help
