If you already have an N6, N7, or N7 Pro extension cable installed in your BMW E46/E39/E53 and you want to upgrade to the Dynavin 8 or 9, you don't have to buy a new extension cable! All you need is this adapter to plug into the existing extension cable at the dash end and plug the other end into the Dynavin 8 or 9!

In this case, you will only need to purchase the "Business CD" E46 version, not the "OEM navigation" version and just add this adapter to your cart.

If upgrading from an N6 to a D8 or D9, you must select either "FLAT PIN PLUG" or "ROUND PIN PLUG" which is dependent upon your car's plug in the trunk end. Please email support@DynavinNorthAmerica.com if you need help with this or have any other questions.
