I debated a lot when I mounted mine. I thought about the sunroof controls but I use those all the time so I nixed that one. The joke cup-holders under the temp controls though (which I've never used) I immediately knew I could do without.
I used a Gadd bracket I had in my stock (I've got another if you find a need for your install) and simply removed the cupholders and then screwed the bracket into place. I think my install is clean, wires hidden and I'm happy with the placement.
The mic-holder is simply slid in behind the center console - no drilling, no glue, nothing. So far it's not popped out once, on road or off.
