You must upgrade to 2.0 beta 13 for visuals to work in tuner mode.

I discovered by accident that they worked in 2.0b11; I had put on the radio as I went through the Harrisburg, PA area and just before I lost that station I pulled off into a rest area on the PA Turnpike and went to sleep for a bit. The radio had been on but on the strength meter.

I woke up, turned on the car, and had visuals. On the radio. Hijack had restored visuals, despite the radio having not been in visual mode earlier.

When I switched back to the player later I needed to restore visuals myself. I verified this when I got home by trying it again, and it still worked.

Can't say what version of HiJack, only "not the one I'm using now"
