I want to add an xm commander via a blitzsafe adapter to my 2001 325i, and also am debating adding a sub. I know the changer wire is on the left of the trunk, but I cannot get the liner out. I removed the black pins but it seems like it is so stiff it will break things if I force it out. Are there any tricks to it or am i missing something. There is a little tray on the bottom of that side of the trunk that i cannot figure out how to remove. ANy help on this would be greeat, thanks.
