No sound, help with Amp

Dear Tundra fam,
I have a 2015 Toyota Tundra 1794 Edition. Stock amp, JBL speakers and woofer.
Out of no where last week, the sound stopped working. When I turn volume knob, i no longer see the volume number go up or down. There is a little icon with musical note with X through it. When I call via bluetooth, i see the call on dashboard but can't anything. No radio either. Fuses were checked and are good.

No idea was caused this, one guy said that the amp died.
New amps via dealership are 1900, there are some refurbished ones on ebay for $400. Or I get invest in a whole new aftermarket system which is more expensive than both!!

Any experience or recommendations?

Thanks

 

Did you check the fuse visually or with a multimeter? If only visually, try swapping the fuse for another the same rating. @AT x AT is selling his full setup from his 2021 for cheap, and wouldn't be too hard to convert your setup over: https://www.tundras.com/threads/oem-jbl-headunit-with-navigation-amp-and-12-speakers.129679/
