I'm having the same problem on my 05 300C. It's not a fuse problem, I've tried all the simple solutions. Looking forward to an answer.

Thanks for writing. After I wrote that, the next time I got in the car, it just worked. Most the time it works and I have had about two times where it was not working.
Other weird things are happening - I noticed that the security light was flashing really fast one night instead of the regular blinking.
Maybe I have some sort of electrical thing that happens once in a while.
Might want to notice if you are having other issues. My car does seem to have them.

Hi! I have the EXACT problem with my radio. I do hope we find a solution. It's been happening to me daily since its gotten cold out-nearly zero here. Someone posted on another site that he suspects my nav is going out and I may need a new radio unit. I'd like to know for sure.
I also have another odd electrical issue like you, but mine us with my wipers. The intermittent is random. The blades will swipe normally, then nothing for about 5 cycles then its line it plays catchup and swipes 5-7 in a row then stops in the middle of the windshield.
