A couple of thoughts:
- what version are you currently running?, check the about sync section.
- the log states you used 3.4.22251 as both current and new/desired version, which results as a reformat (which is ok as long it’s not MY20). Configuring 1.xxx as current version will end with a reformat USB.
- you are using a custom map package, right?. That leads me to believe your unit is not 64GB so storage may be an issue.
- your pendirve is slow and generic “Model: VendorCo ProductCode USB Device”, so yeah, it’s almost a potato. And it’s slow because it took about one hour to create an USB with partial EU maps.
At this point, these are my recommendations:
A) Go to the about sync screen on the APIM, take a picture and post it here (hide the VIN if you care about it)
B) Use a decent and quality branded USB pendirve (not SD card, disk… a pendrive), not a generic one and recreate the USB again. Then, try again.
C) If that does not work, create an interrogator log and run it against the APIM. Post back the results (redact the VIN from the file’s title and content if you care about it).
