Can someone scan the service manual or direct me to a thread that discusses this?

 

as in the center console where the navi is? i have seen it posted on here a few times....
and it is here:
http://acurakid.com/laser.html at the very bottom... it will take a while to load - lots of pictures from my zr3 installation

 

do I need the trim tool?

 

No. I did it with a flat head screw driver. Just be careful when you do it so you don't scratch anything. I would go to a local hardware store and get a plastic putty knife - it will be safer that way and only cost a buck or two.

 

Dude, that is a sweet link! Thanks for posting that again -- i've been trying for a long time to find it ... gunna re-do my MP3 integration this Sunday thanks to your post.

Gotta love this site.
