USING Preset Stations

[pdmike]

I didn't have any trouble setting up my preset stations - AM, FM, SAT.  But I am having trouble USING them.  For example, let's say I am listening to a preset station that I have set under INDIVIDUAL Presets. I want to go to a station that I have set under MIXED Presets.  How do I do it without going through all of the rigamarole of going in and changing first from Individual to Mixed Presets?  I would like to make a change like this using Voice Commands so I don't have to take my attention off the road.  Can that be done?  What is the voice command series of commands needed?
