hi, i have a 2004 mercedes cl600 which had the bluetooth puck available as an option, but the original owner did not order it. i was able to get one and i know it is an easy installation inside the center console. pretty much plug and play. unfortunately i cannot seem to find the connection where it plugs in. i know i have one because years ago i borrowed a friends bluetooth puck and we installed it and it worked properly. this a an MB v60 adaptor which is the small bluetooth adaptor, not the large one which is more recent. i would greatly appreciate it if someone could tell me where to connect this inside the center console. if anyone needs more information i'll be happy to provide it.
thank you

here you go

Those instructions are for cars that are prewired. Adding prewiring is the big deal, and most cars didn't have it.

This is the definitive thread on the subject.
