Important notes

-Some cars will require you to program the car for a CD changer.  From what we can tell cars that do not have a fiber optic amplifier require programming.  All cars with a CD changer do not require programming.
-In you are not keeping the CD changer you must use a fiber optic loop to bypass it.
-In order to make calls through this unit your radio must have a TEL button.
-In order to make calls through this unit you must bypass the factory telephone module if equipped.  See video below for more information.


This is the interface most of you are going to buy.  It does not keep the CD changer. (read the technical info below for more information about programming your radio)

If you decide you want to keep the CD changer this is the interface you need. (plus an extension mentioned below)

If you decide you want to keep the CD changer you will need to connect the Dension unit at the CD changer.  This fiber optic extension will allow you to have the dension up front by the radio while making the connection at the CD changer in the trunk.

DO NOT BUY THIS INTERFACE – While this is compatible with your car this is the original version that does not have Bluetooth.  It is still used for Volvo and Aston Martin but we put it on here because I’m sure someone will come looking for it.

CD Changer and Phone Module bypass loop


If your car has a CD changer and you do not want to do the extra work to keep it you will need this loop to bypass the CD changer or it will conflict with the Dension unit.  If you want to use the Dension unit for phone calls and have a phone module you will need to bypass the factory phone module..  There are videos below that show your how to bypass both of these.

Wire tap tools


This part is the easiest way to tap into your factory power wires for power.  You will need one for each wire and we recommend getting an extra one just in case you drop one where you cant reach.

Pry Tools

These are the Panel Pry Tools that we use in our videos.


Software Update

This video shows how to update the software.  Current dension SW is 65 but we recommend you downgrade to 57 as soon as you receive it.
