i have a 2014 optima lx with just the basic radio. i upgraded my head unit with the pioneer 601ex and it worked great the first day. the next morning i got in the car the digital clock on the dash was out and radio was nonfuntional. i checked all fuses and rechecked the connections and connectors on the head unit. all seem fine. still cant get any power from radio or clock. can anyone help me?? and i also unplugged the pioneer and even put the oem radio back in but it too had no power.

If you checked the correct fuse (audio or multimedia), based on your version in the owners manual, and it was definitely fine then I would suspect the power or ground connection is faulty. Was this installed with splicers into to factory wiring harness or an adapter? The splicers could be a weak connection if used. If the new radios ground wire was added and screwed onto a metal bracket double check that connection. I've also read there is a tiny hole on the factory unit that you can press with a paper clip to reset the radio. Maybe needs that after the swapping back and forth. Good luck!

Not sure about the clock tie in, but this sounds like a good clue there is a fuse you have overlooked burned out that must control deeper. Is anything else like the USB/lighter ports not working? I don't think the Aux fuse would be player but maybe.

Are the lights within the factory radios buttons showing or the whole sha-bang is dead? Have you tried a disconnect of the battery ground for about 30 seconds to reset the whole system? Worth a shot.

Since you used an adapter I highly doubt any wires burned out, just not possible unless was a massive flaw in the aftermarket radio. The most logical issue is a fuse. If it was me I would pull and check every fuse in both the under dash and engine bay. If nothing is found it's a trip to maybe Best Buy radio installers or the dealer for diagnostics. Sorry not more help.
