Thanks for the info, but didn't want to have to read 192 pages to see if anyone had ever had this problem where it just wouldn't come back at all.
I've had the usual glitches and bugs, but never did it just go dead and not recover at some point.
I now have no radio, no MP3, no nav, no hands-free phone, no backup camera, no Sync, and probably no self-parking (haven't tested it). So basically I have an SE instead of a Titanium.
