Remember tuner on DC, MP3 on AC possible?

I mostly listen to the radio when in the car and listen to MP3s when in the office. Every day when I get back into the car at the end of the day my Mk2 always stays on the MP3 player and I have to switch it back to the tuner. Is there any way so that it will remember what mode it was on when on DC and AC? That way it will just go back to that last mode when you switch power sources.

Any ideas or suggestions welcome.

Thanks!

You could have it play an @DC macro to always switch to the tuner when it boots in the car.
