Thread: adding factory nav to a non nav gxp

I have a d7 so i can flash it myself, i found the antenna on amazon for 34$ and ordered it last night. I have both connectors the one for the radio and the one or the onstar/motorolla module for the mic line. i think its as simple as just running a lead between the two and i dont have to do any flashing on the module to use the mirror mic, ie the mic is always listening just not being listened to by the system unless prompted.
