Select how you would like your CarBahn software installed. Dealer installation is the fastest, easiest and most cost-effective option.
Authorized CarBahn Dealer Installation
Your authorized CarBahn dealer has the tools and experience needed to unlock your DME and install the software as part of one straightforward service visit.
- Fastest option
- Easiest installation
- Lowest overall cost
- Professional support
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.
Complete Your Installation
Select any optional upgrades you would like added to your order.
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.
A DME bench unlock is still required. Our team will explain the unlock and installation process when arranging your at-home installation.
Software installed through Bootmod3 or MHD is not eligible for the CarBahn Factory Matching Warranty Program.
