Just got my Discovery used about a month ago, unlocked it without issue. However I can't seem to figure out the radio and how to preset stations. I consider myself moderately intelligent but am being repeatedly proven wrong buy this device.

I have the navigation system and there is nothing in the manual about how this particular unit works, even checked the secondary manual and nothing in there as well...Any help would be appreciated.

 

Figured it out today, there is a menu if you press the radio button twice that allows you to change to Manual mode and you can then set stations.
