Important notes

-In you are not keeping the CD changer you must use a fiber optic loop to bypass it.


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 bypassing your CD Changer)

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.  Optionally if you are not interested in the AUX or USB up front you can leave the Dension unit in the trunk and a bypass is not needed.

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.
