Lost power to the radio out of the blue. The display reads "Ford Focus", and I can't get it to do anything. Checked all the fuses and found fuse 39 blown and replaced it. No change. (And it didn't blow again.) Tore the dash apart to test for power at the radio plugs and found i have no ignition feed, only 1 hot feed(WHITE/ red , I think it was). Unplugged it and disconnected the battery overnight hoping for it to reset. No soup.
I'm hoping someone can tell me which wire should be ignition power. Looked on the Vehicle Wiring page but it wasn't clear to me...
It's an SE with stock radio/cd.
Thanks.

Perfect! Thanks so much.
Soooo, pardon my ignorance, but wouldn't pin15 be ignition (gray/violet)? Why doesn't it say that on the vehicle wiring page?
On further investigation, the fact that the ignition feed is part of the MS CAN system leads me to believe I'm not going to be able to fix this or 'hotwire' it like stereos of yesteryear...
Any idea about why I'm not getting power? Is there some common failure I can't find on the web?

I checked fuse28 which in the owners manual is labeled "Radio (start)" and found it's only powered during cranking. So maybe the wiring is all ok and my stereo is just smoked?
Maybe they don't have a continuous ignition feed anymore?
Thanks for any (more) help!

Update: My wife went to start it and the battery was nearly flat dead. I put the charger on it, started it up and the radio turned right on! WTH?! Like I said, I disconnected the battery before(overnight) in hopes of a rest and it don't work then. Oh well she has tunes now. Thanks
