Well I finally got around to my first mod. Put in a new head unit and rear view backup camera. With the help of the install videos and instructions on this site I was able to get it all in myself. The backup camera took longer than the head unit. Only broke one clip on the trunk panel by the latch but no biggie the panel is secure and doesn't rattle or anything. Just have to be real careful popping that top piece off - really a poor design choice on those plastic trim holder things.
Put in a Sony XAV-63 DVD unit and a Pyle PLCM18SC camera
