To purchase with a Dynavin, go to the appropriate Dynavin BMW model page and select "w/OEM navigation (includes extension cable)" under the "Current Audio System" drop-down menu.

This plug-and-play extension cable kit is ONLY for installing a Dynavin head unit into a BMW E46, E39 or E53 originally equipped with OEM navigation (includes antenna extension cable). If your BMW does not have factory navigation, you do not need this.

BMWs equipped with OEM navigation have their radios and related wiring in the trunk. This cable extends the needed radio wiring from the trunk to the dash greatly simplifying installation in these instances.

The extension cable and antenna extension cable are each 6 meters (about 19.7 feet) long.

Some older cars may require modification to this cable. See the FAQ page question 1c for more info.
