If I DO figure this out, I'm gonna use the knowledge to add a weather radio input to my system! I miss not having NOAA weather when I am driving. I can hide the receiver under the passenger seat and tack the antenna up on the windscreen.

Then I just set the menu option for "phone" to listen to NOAA.

Wish his car was HERE, I'd like to LOOK at it and get to the bottom of it. (Not too good at fixin stuff that isn't right in front of me - I'd been useless when Apollo 13 was in trouble.)
