Sorry for your bad luck with SoundRacer! As our website Listed cars shows, SoundRacer works fine in about 85% of the 450 car models tested and reported. Not many car accessories fit in 100% of all cars, they are all different, that's the problem. See also SoundRacer website for info. Suggestion: Check manufacturer website before buying a car accessory to see if it fits your car. It can help avoid disappointments. And if you tell the car models (and year) it will help us and other customer.
