I was referring to onepuff's comment. I just don't use the drive. Everything is digital and gets transferred by WiFi or maybe memory stick. I can't think of a single time I've use the drive in the car.
The lack of an eject button and any other buttons on the front is what makes it such a beautiful machine. Just trying to keep you from hacking up a piece of electronic artwork. I hope you make it look good at least. Seems like a big waste of time though. I put the mini in my car so i would never have to change discs for music or anything.
Also the way you are installing it looks like it will be hell to remove if you want to take it back in the house to tweek something or diagnose if something isn't working right. I love the dock i made for the mini(thanks BugByte for the inspiration for that one). I can take the mini out in about 2 seconds. It's kind of a pain to add new software in the car and make sure things are working right with a 7 or 8" screen while sitting in the driver's seat.
EDIT: I just noticed my plans haven't been updated with my site link. I'll do that later and you can see what I mean.
