I have a pioneer nav unit and I put mine by the overhead lights but it just sticks up there and I can turn it in all directions. Not sure what your mic looks like but it worked perfect with mine. I also installed one for a friend who had a VW Jetta, but it had a spot for a mic exactly like ours does (for onstar) and I installed it there and it worked perfect. The mic was completely hidden and he didn't have a problem anything. So, I'm sure if you want to hide it there you could (of course, you probably wouldn't be able to use onstar). I could care less about onstar, but the reason I didn't mount it there is because I wanted to be able to move the mic around, and it doesn't bother me one bit where I have it. Hope this at least helps some.
