A DME bench unlock is required. Your dealer handles the unlock locally as part of the installation and labor process. There is no need to ship your DME overseas.

Install Your Software at Home
At-home installation options are available using a CarBahn loaner tool, Bootmod3 or MHD. Call our team to confirm compatibility and determine the correct installation method for your vehicle.
