I went to my dealer today and picked up the Bluetooth Cradle Replacer, p/n B67875855 ("puck"). This is the puck for MY 2003/2004 E-Class and 2004 S/CL-Class. The parts guy came outside, removed a few screws, took up the false floor in the center console, and plugged the unit in. I have a Motorola Razr with Sprint service, and the phone and puck paired immediately. The display still indicated that the telephone was not available. Following the information I have read on this thread, I suggested that the phone had to be "turned on" with the diagnostic computer. Once that was done, everything worked perfectly, including downloading my address book.

You need to be careful about where you place the cord or "tail" of the puck under the false floor. The technician simply routed the cord on the edge of the floor, or you can notch out a piece for it. The false floor is held in place by two small screws on the back end and two more screws under the unit itself. You have to place the cord so the two bottom screws can fit properly. You end up with the puck (about the size of a low profile computer mouse) and about 6" of cord. The puck comes with a velcro mount and a very small bracket for more permanent mounting. The cord is really out of the way, and you have a lot of usable space left. I have never seen a conventional cradle with a puck, but I would assume it must be larger than the puck alone, and space may be sacrificed.

Because the telephone is not in a cradle, it may be a wise decision to invest in a car charger. Bluetooth operation puts a heavier load on the telephone, and batteries will go faster than normal. The car will remain in Bluetooth mode for about a minute after you turn off the car, and my telephone beeps and indicates that the MB Phone system has disconnected. If you open a door, the system turns on. All of this is in the manual.

The service guys had little knowledge about anything relating to telephone installation or configuration. The parts guys had a little more knowledge, and in fact knew what a puck was, but were not familiar with this particular one. They had it in stock, and went outside to my car and did the installation. I think they were curious to see if it would work "without the normal kit stuff" and told me if it didn't, they would refund my money.

The hands free telephone system works great, and was very, very easy. You will need a Star computer to make your car see the telephone. There appears to be no problem with Sprint, even though it is not listed on the official list. Sorry for the long post, but I wanted to share my experience with some of the issues I have noticed in this thread. Bottom line, the puck works as advertised. Thanks for the assistance from this thread.
