Hello all. I am new to the forum and just picked up my E 55 last week. One word... AWESOME! I know I am still in the honeymoon phase, but I am really enjoying the car and plan to long-term.

I am trying to get the Bluetooth working and have searched all the related forums I can find.

Here is my question. It seems I need the puck, and the latest and best part # is B 6 787 5878. I have the connector in the armrest, but it is on the back wall rather than flat like I have seen others. Will this device fit? It seems to me it will be too large.

Any advice is appreciated.

I just upgraded my 07 E550 to Bluetooth with the puck # you mention. Mine fits very snugly/tightly in the rear of the arm rest. Because it's so tight with very little vertical clearance be very careful not to force it or you'll break the PLASTIC connector.

And almost all of them on Ebay are used.

I ended up ordering the newer B67876131. There is a Benz dealer in texas on eBay selling them new for $358. Not bad.

These cars are simply awesome. Wolf in sheeps clothing. Can't get over it.

Thaks for the help.

A lot of us have 8 cylinder envy!
