Installed the Midland MXT500. Tapped into the Radio fuse with a fuse tap on the passenger side for power. I would have thought that there wouldn't be power unless at least accessories was enabled but the radio still turns on? The radio has an auto-off feature, so I'm not concerned, but was surprised it still had power with the car completely off. I guess the fuse box is wired to the battery and not after the ignition?
