D. Firmware update
We constantly improve our firmware, so it is highly recommended to perform a firmware update first,
if an issue/problem arises. The update procedure on Gateway Pro BT is quite simple.
Go to our website => Support => Downloads => Firmware update and make a filtering on Gateway Pro
BT using the dropdown menu, choose the latest firmware and download it.
Extract the G31B_UPD.rom file from the update package, copy the file to the root folder on a USB flash
drive, connect the USB drive to the Gateway Pro BT while it is powered up (ignition ON). Copy a few
playable music files to the USB device, to the root folder also. If there is an iPod connected to Gateway,
please disconnect it before connecting the USB drive.
The update procedure will start automatically within a few seconds and takes approximately 2
minutes. During the update procedure the Gateway Pro BT will restart a couple of times. Do not
disconnect the USB drive or turn the ignition OFF (!).
When finished, you may need to select the Gateway again as source from the Head Unit (car stereo).
After a successful update the G31B_UPD.rom is deleted from the USB flash and the new software
version number will be visible in the Gateway Settings\About menu.
Test the Gateway Pro BT functions.
Please note: Although we do support playing music content from a USB hard disk drive, for the
firmware update please use a USB drive.
Important note for Peugeot or Citroen users: Start the engine before performing a firmware update
in order to avoid the activation of ‘Economy mode’.
