Fact! No change after 150, it's already been assigned a VIN # at this time so that VIN actually describes the car in code... I tried like bloody hell to add in B&O sound and had called everyone under the sun, dealer, bmwna, product specialists talking to factory. I am one persistent dude.... To a fault. I was not able to change after 150 status. You will see that car will be at the port done in like 5 days from 150 status
I then heard the B&O in person after I was told no and was not impressed.i thank bmw's discipline now for saving this persistent boy $3500 smackaroos!
