I have the 2010 FWD, base model, no tech.
Other day I turned my stereo off (CD player), everything normal. Did not drive on the weekend.
Today I turn on the stereo - nothing. No display, no play.
None of the functions worked, radio, Bluetooth, cd, nada.
Tried to check fuses but can't tell for sure which it might be.
The manual map does not identify a fuse for stereo as such so I don't know which it might be. Anyone know the fuse no. for the unit? I'll take it to the dealer when it's convenient, I'm still under warranty, LOL. (see my other thread :-)

 

I looked through mine and also could not find the fuse(s). Looks like someone else had the same issue a year ago too:

FALSE ALARM!!
Well what do you know? I turn on the car today and the stereo starts right up like normal. WEIRD. But I will take it.
The only thing I can figure is that maybe the HFL was trying to make a call or take a call or something like that, because the HFL cuts out and takes precedence over the stereo. So for now my system is working.
Luckily I did not run to the dealer right away and look like an idiot! (No funny comments thank you. :-)
