Instructional video for the Cessna Longitude

Can anyone suggest a quality instructional ‘YouTube’ video for the Cessna Longitude, that doesn’t shortcut procedure. There appears to be inconsistancies in the recent (March 2023) uploaded videos. Just looking for a methodical walkthrough with explanations video that doesn’t miss out what to do with the ‘trim’ for example. Or how do I change the runway take off heading when it isn’t available to me in the MFD settings…
I use simbrief as well and that would be good if included.
