Kia Troubleshooting Questions? Ask a Mechanic
The accessory fuse 10 amp and the radio fuse 10 amp. located in the engine compt fuse box.
We have many that ask questions that are not aware that there are multiple power sources and we also do not know the mechanical aptitude of those asking questions, so please bear with me is if I seem to state the obvious to you. I start small then move to big. If you overwhelm some people with the first question, and they have no mechanical aptitude, the leave unhappy.
So you have verified you have continuity but did you verify Power to the fuses in question. If you did, then the next step is to pull the radio and verify power to the Yellow/Black and Yellow wire at pin's #1 & #2 with the key in the on posistion. If you have power to these pins, then you have a radio issue. If you do not, then you will need to back track. I attached a diagram below.
