HELP: No FM/AM, Audio amplifier?

Hello Prius team,

I recently bought a Prius Hybrid 2015, One, I checked the radio and AM/FM all channels are just static. You can BARELY hear one channel, but that's it. The CD, Bluetooth and AUX all work fine except the radio. Not from the area as my other Toyota receives a strong signal, I took off the antenna from my Corolla and attached it to the Prius, still the same, and I realized it's not from the antenna since my Corolla had a strong signal even without the antenna attached.
I read that it could be the Audio Amplifier. Could it be anything else? Also, where is the audio amp located in a 2015 so I can at least make sure it's there and there isn't any disconnects.
What are some other things I can check at home without paying a mechanic?

Thanks for your help in advance!
