This official BMW Bluetooth information webpage is a great source of information for supported phones, product benefits etc. The section of BMW's Bluetooth website titled Supported Vehicles is a little confusing as it does not talk about the ability to retrofit older model BMWs with the BMW Bluetooth system. Retrofitting BMW's Bluetooth system provides you the same features and functionality that you would otherwise have with the new car BMW Bluetooth system.
Bimmernav.com's Bluetooth retrofit kits are built of BMW Original parts based on the specific Build date and Model of BMW. Click the link below for detailed information on your model of BMW below for detailed information.
