i have the same problem but different. i don't have the factory radio for the car so i can't get the serial number off the factory radio to get the code. i have the radio out of my other integra so i put that in there and tried that code and it doesn't work. i called acura and he said that you have to have the serial number off the original radio from the car. so i want to know if im fucked or is there something i can do.
