I looked thru the Interrogator file and don’t see any issues with the asbuilt or the Sync installation. There is plenty of free space, even too much I think. The APIM is a rather current version, JR3T-14G371-CED, which will handle the upgrade.
You have 5.8GB free, which was odd to me. You missed a map file, you have 8 installed out of 9. Everything else looks fine, but that is why the map background is missing. I don’t know which one it is, but it’s one of 4U5T-14G421-CHD, -CFD, -CCD, or -CED based on the file sizes.
The best thing to do is either perform the whole installation over (refromat is about 30 minutes) or install the maps again stand alone (about an hour and a half). In the end, it will take about the same amount of time because you will need to downgrade to 3.3.19052 to run the reformat tool.
Use this tutorial as a guide, it also has all the maps listed.
