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.

Selected add-ons will be added to your cart with the software. Warranty eligibility and coverage are subject to CarBahn’s warranty terms.
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.
