How do you use the tuner instead of channel preset navigation on a pioneer DEH-P8600mp car stereo?

Hi - I somehow set my Pioneer DEH-P8600MP car stereo to navigate satellite radio channels only by channel presets. I can't navigate from category to category. If I push up or down on the multi-function button, the tuner goes through the various station presets. I used to be able to navigate through the satellite radio categories by pushing up on down on the multifunction button. Also, I cannot enter station numbers using the remote. If I push a number on the remote it goes to the preset. If I push a number that does not correspond to a preset, nothing happens. Thanks in advance for any help.





Dave|||I'd suggest using the "search" option vs. the preset. It's usually the same option that changes tracks in the cd mode.
