The USB works, but the computer write, there is no file on the stick.
I think i have to go to a local dealer.
Before taking your i3 to a dealer, check the current media and phone software versions as displayed in iDrive. The versions currently on our 2014 U.S. BEV are MN 003.013.001 & TN 003.013.001. Media and phone software updates are also included in the system software updates that can be installed only by BMW dealers. I successfully installed media and phone software from a USB drive only once. My subsequent attempts have always failed because a system software update had already installed the same or later software versions.
The Readme file associated with UPD05081.bin describes the software versions included in UPD05081.bin:
▷ HN 003.255.080 & MN 002.255.071 & TN 002.255.080
▷ HN 003.255.080 & MN 003.001.002 & TN 003.255.080
▷ HN 003.255.080 & MN 003.003.001 & TN 003.255.080
▷ HN 003.255.080 & MN 003.009.004 & TN 003.255.080
▷ HN 003.255.080 & MN 003.011.002 & TN 003.255.080
▷ HN 003.255.080 & MN 003.013.001 & TN 003.255.080
The versions installed depend on which vehicle you have. If the versions already on your car are later than those in UPD05081.bin, iDrive displays a confusing message that doesn't describe the problem. Another problem is that it isn't clear to me from the version numbers which is later.
I'm guessing that your i3 already has the same or later media and phone software as that included in UPD05081.bin.
