Here you can download the latest version of firmware for your GROM-USB2, GROM-USB2P or GROM-AND2 interface.
To apply the firmware do the following:

  • Rename file to gromusb2.hex
  • Put the file on a USB stick into the root of the drive (as shown below)
  • Turn on the ignition and attach the stick to the device
  • The light on a stick should blink for several seconds and then stay solid
  • The firmware update is done. Ready to use!
  • Turn ignition off and then on for stereo to recognize the new firmware
  • Make sure you remove gromusb2.hex from the stick to avoid unwanted firmware change later !
