There are a ton of Youtube videos that would be helpful. Drew Brashler's channel comes to mind. Keep in mind that version 4 firmware makes some significant changes, so older videos will help but won't match precisely. The X32 and Midas M32 family are basically all the same, so someone who knows one model, knows them all. That's one of the nice things about them, along with a plethora of people that are familiar with them.
