It is very simple, it is being held by two screws, one beneath the door open handle with a little tab and another on the grab handle.
Once you unscrew it, the trims are held by 10 clips, you need to apply a lot of force to get them out the first time, especially if youve been riding for a while. They sink in good.

Once you pop them out of the place, make sure you unhatch the door handle extension, very simple downward motion to un-link it.
After that unscrew the speaker (3 screws) and pull the connection out. That's it. Now swap.
