Hi I have a2007 gl450 with the phone connector inside the arm rest and I am trying to fit a Bluetooth puck# b67875878 but when I plug the puck in nothing happens no flashing or solid blue light from the puck. Does the car need to be coded or is it a plug and play deal. Thanks

Did you ever figure this out. I have the same problem.

As I recall from years ago when I installed our 'puck' it is plug-and-play. After it is connected do the following:
HOW TO ‘PAIR’ a cell phone to the Mercedes
On head unit - select TELEPHONE
On IPhone go to - Settings: Bluetooth
On the ‘PUCK’ press and hold the Mercedes ‘Star’ Emblem
IPhone should ‘find’ the “MB” Puck signal
When it does, select ‘accept’ on the IPhone
Enter the code [password] ‘MBUSA’ (in numbers)
The phone should pair.
Wait a bit for the car to get the address/phone book from the phone
If that doesn't work phone your nearest dealer's service advisor and ask for his help.

+1 had puck in my 2008 GL worked great. The code you need for pairing is MBUSA.

The wiring harness going to the puck was split on my car. I resoldered the wires together and have had no problems since
