Why my radio and nagational screen don't work and both of my front seat don't mo

I check all the fuses end the glove box and end the truck all of them good watt else to look for

OK, now it is time to check for power at the switch for the seat, the connector for the NAV unit. Removing the unit is a pain, so I suggest reading up on the procedure. There are about 1,000,000 tutorials out there that show step-by-step. Also, when you are checking for power at the switch, if power is present, move to the electric motors and see if power is sent to the motors when the switches are pressed to move the seat. My guess is there is none at either.

Thank you so much it was the fuses at the very top of the fuse box

Excellent!! I'm glad it worked out!
