Screen size and APIM firmware or software - Ford / Hardware - CyanLabs Official Community
Is this the 5U5T-14G371-LNC unit installed in the vehicle? 16GB will not support NA maps package, and MEM_ERR01 shows that. Not enough space.
When you reformat, you might get a black screen. Which screen is connected to the unit? I know you replaced it with the 8" version, but you didn’t say which part number you used in the last thread.
