Radio and bluetooth work, but no sound coming out of the speakers? Would there be a separate fuse just for the speakers? Obviously have not checked yet......other ideas......

That is usually a problem with the head unit. I would in fact remove the radio fuse for a few minutes and see if that fixes the problem.
If not, take the car to the dealer. It should be under warranty. Most likely it will need the radio replaced.
Another note. Check if you have an amplifier as well. Check the fuse as well. Or the amplifier itself could be the problem.
