Change radio station from steering wheel

When I press up/down arrow switches input source(Stupid Sirius, iPhone), I want to change radio station How? No options in infotainment settings.

 

Edit: I was wrong!

I Googled and found this:

Yes, you can use the steering wheel controls on a Toyota 4Runner to change the radio stations. The switches on the left side of the steering wheel control the audio system. For example, you can use the MODE/Hold button to turn the audio system on. You can also use the up and down controls to go through the pre-set stations (AM/FM/XM) unless you press and hold

 

The steering wheel buttons will change between presets. Any channel for which you have a preset is accessible from the steering wheel.

 

Hmm thanks! I dont have presets, guess have to look up how to set. I wish I could scan.

 

You can configure up to 36 presets. They can include any mix of bands.
