You checked fuses and they're all good. So might be time to pull the radio, and check its fuse. Generally they have their own at the back, but while your doing that. Check all the wiring to make sure it isn't burned, melted, rubbed through/chaffed. Cracked or in any way defective. Check all your power wires and earth points.
If your vehicle has them, check the fuses and relays under the bonnet (hood) also. Most vehicles have two sets of fuses.

It's in the engine compartment IOD#2. It's a black module with two fuses in it. Take that module off and replace the 20 AMP one.

Sounds like the splines on your transfer case gear are ground down

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.
