Fuse Replacement?

[jimbau]

My aftermarket radio quit working all of a sudden this past week, a long with the sound from the turn signal and there is no sound when you hit the lock button getting out of the truck like there used to be. I was curious if this was possibly something as simple as them all being linked to one fuse and if so could someone possibly tell me which one or offer a suggestion as my owner's manual has disappeared.

 

Thanks
