BMW baseplate 84109158069
phone snap-in baseplate I purchased this for my retrofit a few months back and installed this, works fine, however I upgraded phones and uninstalled the snap-in and baseplate. The baseplate can be used in conjunction with combox retrofits, 6nf, 6fl, or if you have none of these you can install this with your phones snap-in and utilize the cars cellphone antennia.
