2005 E320 CDI phone craddle
 

Bought my benz in dec, pretty happy with it....except the "after market?" bluetooth phone cradle in arm rest. I can't find anything on youtube or googling info on this cradle. It's a motorola cradle, and snaps in to cradle. Might add rather cheaply made. It is very hard to snap into place and is currently lose, can't tell if little metal piece is broke or not, to hold into place. This is a horrible place for cradle, losing the space in arm rest, imo, but ridiculously expensive to replace with bluetooth radio for car, virtually impossible to replace current radio.
Any pics of how this should set in place? so I know if something is broke or not. Small pieces of metal (clamp) at front of device.
