How do you know what audio system you have?

Aren't the options listed on a piece of paper stuck under the trunk lid?

Yes, they are.

You've most likely M490 if you have door subwoofers, and yes, you'll have dash tweeters.

M490 means an amp in the front trunk and it will have an M490 sticker on it, but you'll have to unbolt it to see it.

Agree you should have an options sticker on underside of front trunk lid.
