How to update your X35 bike

01. Download the ZIP file, unzip it, and copy the unzipped files to the root of a FAT32-formatted USB stick. Ensure that the USB drive contains only these files for a correct update execution.
02. Connect the USB stick to a GCU (the GCU must be turned off, disconnected from the charger and the bike).
03. Turn off the bike if you have not already done so. Next switch on the bike.
04. Plug in the charger.
05. Connect the GCU with USB stick to the charger and wait 10 seconds until the GCU´s light stops flashing.
06. Connect the other end of the GCU to the bike’s charging port.
07. Wait until updates are completed by monitoring the GCU status light:
  1. Steady or intermittent yellow: Updating, please wait
  2. Intermittent purple: Auto-updating, please wait
  3. Steady green: Successfully completed
  4. Steady red*: Update failed entirely
  5. Alternating green and red*: One task has failed and one has been successful
  6. Steady white: Update package has been ignored
08. Unplug the charger from mains power, 9. Turn off the bike. remove the GCU from the bike and disconnect the USB stick.
09. Turn off the bike.

*In cases D and E, you will need to disconnect in order to repeat the process. Disconnect the GCU from the bike and the charger, turn off the bike and repeat steps 4-9. If the update process is still unsuccessful, send the GCU_log.txt file located on the USB memory stick by email to MAHLE Smartbike Systems to analyse the problem.
