Troubleshooting BMW Latest 2021 Map Update Failures

Updating your BMW’s navigation system is usually a straightforward process, ensuring you have the latest routes and points of interest. For owners with Connected Drive subscriptions and access to the BMW Latest 2021 Map Update, the process should be seamless. However, some users have encountered frustrating issues during the update process, particularly when using a USB drive. This article explores a common problem experienced during a BMW 2021 map update and potential steps to resolve it.

One user attempted to update their system using a new 64GB USB 3.1 drive, formatted to FAT32, after their previous 32GB drive proved too small for the larger 2021 map files. They downloaded the VIN-locked update file using the BMW Download Manager and transferred it to the USB. Upon plugging the USB into their BMW i3s, the update process commenced, but unfortunately, it failed at around the 20-21% mark. The system displayed an error message indicating a “corrupted” file.

Undeterred, the user reformatted the USB drive, this time to ExFAT, and repeated the download and update process. Regrettably, the result was the same. The BMW map update failed again at approximately the 20% completion point, with the same “corrupted file” error message.

This persistent failure led to further complications. After the failed attempts, the car’s navigation system ceased to function correctly. Instead of providing navigation, the iDrive screen continuously prompted for a USB drive to continue the update. This persistent prompt effectively rendered the main screen almost unusable, making even basic functions like CarPlay difficult to access.

Faced with a non-functioning navigation system and repeated update failures, the user attempted the entire process once more, downloading a fresh update file. Despite these efforts, the BMW Latest 2021 Map update consistently failed at the 20% mark, reinforcing the “corrupted file” message.

At this stage, with troubleshooting steps exhausted, a dealership visit appears to be the next logical step. The vehicle, being only six months old, remains under warranty, suggesting a potential hardware or software issue beyond a simple user fix. Speculation arose whether the use of a USB 3.1 drive might have contributed to the problem, or if the car’s navigation unit itself was experiencing a malfunction.

For BMW owners encountering similar issues with the BMW Latest 2021 Map update, especially repeated failures and “corrupted file” errors, seeking assistance from a qualified BMW dealership is advisable. They can diagnose potential underlying problems with the iDrive system or provide guidance on alternative update methods. Further updates will be provided pending the outcome of the dealership visit.
