My favourite way to "tune" the tuner, is to use Hijack's knobseek magic "button". It's normally available from the Hijack PopUp0 menu: go into the main hijack menu, and assign PopUp0 to the (short) Knob Press Definition.

Then, tap (short press) the knob, and rotate it until KnobSeek appears, and tap it again to select. Now, the knob is a manual tuning dial, just like on a normal radio.

If you like it, you can use ir_translate to assign KnobSeek to one of the stalk buttons. This way, a press of that button will activate it, and twisting the stalk will tune forward/backward.

Cheers
