I currently have the RF 6 disc changer installed in my GSR, I'm looking into getting a factory nav, will that include bluetooth capability by default? will I need to install a microphone somewhere?

 

I think the RF navi & Bluetooth kits are sold separately and are pretty much 2 completely different types of install. Might be easier to do all at once, though.

And the microphone gets routed and installed up in the overhead map light.

 

It looks like my light already has a mic, or is that just normal... there are little holes between the lights. Currently I have the 6 disc in dash

 

bluetooth is a separate module. The NAV integrates with it but does not include it.

 

You would need to get the bluetooth kit if your car didn't come with it from the factory...
