This is petty, but is there any way to default the "Radio" button to something other than satellite radio? I didn't want to keep paying to listen to the same 10 songs so I let my sub expire. It's kind of annoying to have it go to an ad every time I hit radio. Can I set it to automatically go to bluetooth?

I think in the engineering menu you can turn off the options like weather radio/sat radio... I'll look when I get a chance.

Sorry, I found the menu I was thinking of but it doesn't appear they can be disabled.

Mine goes to the last thing I listened to, so FM if I hit the radio button and bluetooth if I hit the CD button if I last used Bluetooth as the source.

Me too ^ Always goes back to whatever I was listening to last.

It should always go back to the last system you were using.

Which is always

Spice Girls - Wannabe

on track repeat

That's so weird. I would assume the same thing, but mine always seems to go back to the satellite radio setting when going from NAV to Radio. I'll need to play around with it and see if it's all the time or just after restarts. I know SAT wouldn't be the last listened to setting considering all that's on there is an ad to buy SAT radio..

If you go into audio at the top of the screen (memory shot here without looking since I don't ever get sat radio) you select radio there and not sat. Will that fix it? Just a guess.
I do know for sure that since I have no sat and I go from Nav to Radio it defaults to the last AM or FM station I was listening to as others have said.

Weird. When I press radio it goes to radio. Same with all the other buttons on the sound system.

Sorry for the delay, did some more research.

Using the Comand knob, if I go to the Audio option, it goes to the current playing (Bluetooth in this case). If I press the RADIO button on the dash (coming from any other option like NAV or PHONE), it goes to SAT regardless of what is being played.

When you are in the Audio menu did you change it to radio or leave it in Sirius?

I learned something new! I didn't realize that the CD button went to bluetooth.

Ok so while waiting for she who shall be listened to today I took some time to play.
First, repeated push of the RADIO button scrolls through all forms of radio available.
It replicates what happens when you push down on the COMAND button go up to AUDIO and scroll through the list of radio options.
I apparently can still pulls some Sirius Radio so I set it to a station.
When I went to other functions such as Audio>BT and played music off my phone, when I hit radio it went back to Sirius on the same station.
When I had it on FM then went to BT and back it came back to FM on the same station when I pushed Radio.
Using the Radion button, each time it scrolled to the next radio format it came back up on the last station I was on.
Not sure why you are having an issue here. It seems pretty straight forward to me.

I figured it out.

As Alex stated, pushing RADIO scrolled through the available radio options and would save on the last used. My assumption, which was wrong, was that all the available AUDIO options were under RADIO. Actually, pressing DISC is the button/menu that I want if I want to go back to bluetooth audio.

You are joking right?
I am still trying to find a CD button on my dash which ain't going to happen because it don't exist!
I have a DISC button which takes me to the CD and DVD player but pushing it does not go to BT. It scrolls through the discs loaded into the system.

Same here. Of course, I do have a PFL, which is getting to be pretty long in the tooth as far as the electronic gadgets go. My car doesn't even sync iPhone contacts!

No not at all.
You're right though, it is a "DISC" button.
And yes, it takes me to BT audio.
