No power to stereo/navigation!

[V8Limited4wd]

So my truck was sitting in the hot sun for the past 7 days and until today I never had an issue with the car battery(original from 2004). I was able to get a jump from a car but there is no power getting to the nav/stereo, everything else works. I'm thinking it's a fuse under the dash, anyone know which one it is?

I did try a portable jumper but it didn't have enough juice to start the engine, not sure if that caused the issue.
