I just got a '06 GS300 today. I haven't got a chance to play with it but I see some kind of microphone on the left. Do these come with Bluetooth ?
Also what are my options to upgrade the radio and audio

 

That's the speaker for your phone when Bluetooth is connected to your phone. Only Phone will work with Bluetooth . A.s for upgrade look up in Forums Tesla display Head radio replacement.I have the factory in mine not sure why you would want to replace it. Mine sounds awesome. Mark and Livingston system.

 

Radio radio sounds okay . I see there's an aux wire inside the glove compartment I can't figure out how to connect to it. Can someone tell me how I connect to the radio

 

The car does not have Bluetooth Radio. You need a adapter. I have a monster cassette insert i use than plug my phone into the chord and set to tape. Then you can Stream Music. NO Bluetooth just for making calls

 

 

Thanks I will look into this. For now I want to get the aux to work. I found a aux wire that pops out into the council under the armrest but I can't get it to play on car audio. I tryed to find cd2 but only shows cd1. Is this after market? How do I get it to work

 

You have a 6 disc changer press the disc button and load in the Disc lol. Don't you have a manual. You can find it in line.

 

I know how to use cd lol. I'm trying to figure out how to use the aux. I think it's aftermarket

 

Do you have a cd in the changer?
Try removing all CD before trying Aux
My factory Aux is in the glovebox and I can't use it with a CD in

 

I do have a cd changer. No CDs in there. I looked on YouTube and it shows that to get aux working you have to go to CD2 . No matter how many times I press CD it only stays on cd1

 

I I figured it out. It's the GTA car kit. it's aftermarket and that's what the microphone is that I was asking about. That's also what the aux cable is that I was asking about. There's a lot of different car kits and I ran into a video of this one. You have to put it on CD disc one for Bluetooth disk two for aux . This is for anyone that can't figure it out I'll put it here so you don't have to take so much time to figure it out
