Truck was at dealer yesterday to have back up camera installed. Now the radio appears to not be working. Wondering if they blew a fuse. Looking to find that fuse to check it

 

Please provide the model and year of your truck. Also, is the backup camera using the infotainment system display for the image or some other display? Does the backup camera image display properly? Did you try turning the radio on to make sure it's not just that they turned off the audio while checking out their work?

I'd be going back to the installer, and having THEM fix it.
