I'm trying to install the iPod adapter and I'm following the instructions posted on http://www.e46fanatics.com/howto/howtodetail.php?howto_id=25 to remove the silver trim. The only problem seems to be that I'm doing this with a considerable amount of force and the trim still won't come off. I'm also worried about breaking off a piece of plastic or something. Supposedly it's held on by friction but there seems to be something it's latched on to. Is there something else that needs to be removed?
