I have an 06 Scion tC and I got my hands on an Avic F900BT but Im about to have it installed by circuit city tomorrow mourning ( Huge discount ) and I see Im missing the mic. The person who sold it to me told me that it's built in but thats not what im reading online. Can somebody please let me know. Also Im not gonna have it installed either way if its missing but I guess I could just have it put in when I put in my ipod cable later on as well right ? Also anybody here who might have a tc with an avic and has figured out how to get the radio door closed. Any help would be greatly apreciated.

The mic is NOT built in to the unit, it plugs in to the back. Yes, you can have it done whenever you feel like it, the only downside is that not having the mic takes a lot of features away. You won't be able to get any use out of the bluetooth feature or any of the voice commands.

OH CRAP! Does anybody know where I can buy one in queens NY. I can do the whole ebay thing but instalation is tomorrow! Also can I get any old microphone say from a PC type thing ?
