My 2000 4Runner SR5 has a power antenna and an after market head unit from Boss. It’s my daily driver and I’ve never had any issues with the antenna or stereo. I started it the other day and neither the antenna or stereo have power. I’ve replaced the ACC fuse but still no power. I’m definitely no expert with vehicles but love learning how everything works and learning to fix things. I’m going a little crazy without music on my drives so any advice or trouble shooting tips are greatly appreciated!! Thanks

 

Antenna will be controlled by head unit, have you pulled the unit and tested your battery and accessory feeding the unit? Does the unit have a separate fuse?
