Thanks.
Well, that’s REALLY odd…
Are you a heavy car play user?.
At this point, your only option is to follow the legacy workarounds for that condition, those are located here → APIM Sync Settings Not Saving, VER_ERR08 Errors, Cannot Perform Master Reset or Upgrades/Updates (Solved)
From what I remember, what used to work was trying the SR → SR → MR combo multiple times.
Also, that’s a no-MY20 APIM, so it could be reformmated. Since the interrogator log runs, if the legacy methods do not work, you may consider trying to reformat the unit.
