What's the best way to install an aftermarket radio while still being able to use my hvac controls and everything?

Take a look on Crutchfield to see what is available.

I have but everyone keeps saying I wont have my hvac controls. Because I have the nav radio.

If you don’t want to replace it, see if this fixes it:

No Radio, No UVO, No Bluetooth, No Camera, Black Screen...

I started my 2012 Optima EX this morning and started to back out of the driveway. The rear camera usually displays, but all I see is a black screen. I tried the radio, and it doesn't come on either. No UVO or Bluetooth. Could I have blown a fuse somewhere? Where is the fusebox located? Any...

I had the same issue and this fixed it. Sitting in the drivers seat, near your left knee is the access panel to the fuses. There is a yellow carriage that holds the radio and something fuses. I pulled mine momentarily and pushed back in and it started working again.
Hope this helps...and if it doesn’t, good luck with your search.
