How it works


The Gateway 500S BT works by emulating the CD-Changer in the vehicle and enables you to use the original radio controls.

It utilizes the MOST™ (Media Oriented Systems Transport) system, a high-speed multimedia network technology optimized by the automotive industry. The serial MOST bus uses a ring topology and synchronous data communication to transport audio, video, voice and data signals via plastic optical fiber (POF) (MOST25, MOST150) or electrical conductor (MOST50, MOST150) physical layers. MOST technology is used in almost every car brand worldwide, including Audi, BMW, Jaguar, Land Rover, Mercedes-Benz, Porsche, Toyota, Volkswagen and Volvo. SMSC and MOST are registered trademarks of Standard Microsystems Corporation (“SMSC”), now owned by Microchip Technology.

The Gateway 500S BT connects to the MOST™ ring as a CD-Changer therefore if you do have a CD-Changer already installed in your MOST™ equipped automobile and would like to use it after the installation of the Gateway 500S BT please choose the "Dual FOT" version of the device. If you do not have a CD-Changer or you do not want to use it any more the "Single FOT" version is just the right choice.


We strongly recommend having your device installed by a qualified car electronics technician. Dension does not warrant any installation work or assume liability for any damage caused due to negligence, improper installation or operation. Please find an installer in your region by clicking here.

The Dension Gateway 500S BT connects to the optical system of the car. While this does not alter the electrical system of the vehicle, the connection is not different to connecting other aftermarket accessories like phone kits, or other entertainment electronics.

  • The installation of a Dension product does not require the modification of any electrical component of a vehicle.
  • The installation of a Dension product does not require cutting cables, soldering, or any irreversible action to the wiring of the vehicle. (Except 12 Volts connection in some specific installation cases.)
  • Dension products can typically be removed without any trace (e.g. in case the vehicle is sold), except from the mechanical installation of the cradle option (if used and installed certain ways).
  • Dension also serves several car manufacturers as an OEM partner with products offering very similar features based on similar technology as the consumer products of Dension.
