We can now fully replace the radios in the above cars, keeping the stalk control & PCN (rear parking) working fully. We also have the ability to remove the original BMW radio and stop the car from reporting errors when the car is taken back to BMW for a service.
If you replace the radio & attempt to get a service & software updates BMW diagnostic will say no! But we override this system, and the BMW diagnotics will work FULLY!
A very nice upgrade with no downsides.
We can also retrofit ANY parts to the BMW 1 & 3 series, as if it left the factory with them, EVEN if your local BMW dealer said NO!
