PLEASE NOTE: If you are Retrofitting a 2000 or newer BMW that is currently equipped with a separate BMW SES Voice recognition module you will need to remove this module and replace with the SES jumper plug. The BMW Bluetooth system has Voice Recognition built in and you can not have two voice recognition systems in your car at once. If your BMW does NOT have SES Voice recognition already you "should" have an SES jumper plug in place from the factory, although you should always verify to be sure. See BMW Doc on SES jumper plugs

SES Jumper plug Connected. Top Picture shows older version, I prefer the newer part number shown below.  I only sell the newer version SES plug as shown below
