d2b problem?
OK, I am still having problems with my installation kit on my 2002 c240. I believe it may be a d2b problem. I plugged in the open d2b plug in the trunk into the PSE unit (all other connections seem to be correct.) I still have message 'NO PHONE.' So I try unplugging the Bose amp d2b connector and plug that into the PSE unit. This works, but of course I do not have audio. So is there a d2b loop problem with the open connector? Am I missing something? I checked the service diagnostics (mute, #1, #3,) and all d2b connections match. I also checked the phone line in the back of the head unit and that is also correct. Any ideas? Thanks in advance for the help.

You need to remove the dash panel that houses your radio/headunit and wire the phone fiber into the loop, e.g., head-unit out fiber into the phone in fiber, etc.
