Accessories

I just bought a 2003 Mazda 6s and was wondering what additional accessories I can find to install on the car.

Things I would be interested in are:
-Cargo net for the trunk
-Homelink system to control all the garage doors
-Is there an easy way to play my MP3s? Looks like installing an aftermarket stereo is out of the question.

They have all those through mazdaspeed and all that gravey stuff.

I know METRA just released a aftermarket dash kit so you can keep the mazda 6 look and put a REAL stereo/cd player/ mp3 player/dvd player in the dash.
