Towing Side View Cams -unable to write to IPMA

[DiveController]

New to Foracan but have a basic working knowledge. Tried to write Livnitup’s IPMA and APIM Data. Toggle switch created in Drivers Assitance but greyed out. Found values written to IPMA would not stick after writing. APIM value good.
Thanks for insight
