Please help! Klyde head unit in 2013 Hyundai sonata can't get the sound working

Hello

I've searched and tried plenty, and maybe this was covered but I can't find anything that works..

I recently bought a Klyde unit for my 2013 Hyundai sonata with dimension stereo and stock amplifier..

The wiring seemed simple enough, but I cannot get any sound through my speakers.

I did quite a bit of troubleshooting and even got a replacement canbus decoder from the seller but still nothing..

Is there a simple solution that someone else knows or should I just return the thing and get a different one..

Thanks a million I'm stumped
