Don't tell me - did you trap the seat belt in it - I have at least twice - the dealership replaced mine on good will,they said another coupe owner had it happen 4 times ! - they tend not to retract fully.

Get one from a main dealer an dthe door panel has to be removed and the speaker grill has to be melted or chiseled off. The new one has to be melted on. I use a soldering iron.
