Pictorial narration where and how I installed the mic and GPS antenna. The mic form is stuck with superglue (on the sides and not on the tip) where the factory mic was installed. I did the ultimate test of mic reception- called wife and she could hear me very clearly even when I sat in the back seat and speaking in a normal voice! GPS stuck on the passenger side roof- the reception is immediate!

There was no need to remove the A pillar or the glove box. A word of caution- make sure the tip of the guiding wire (cloth hanger) will not catch onto something such as the airbag curtain or other cables. Use pliers to flatten the tip. Be gentle when pulling the cables through.
