i just bought my tsx used and it didn't come with the user manual with the car but then i had a issue to change out the battery and then i started back up my car and it worked fine but i noticed that i needed the code to start the radio back up... i think its the anti-thief stuff but i have no idea how to start it back up i called up the acura dealership and they said that i need to look in the user manual book that i don't have and i told them and they just said just bring it in so they can take a look at it and when i took it in the were opening my glove compartment to look for a "serial number" r something like that and he couldn't find it so he said hes gonna have to take out my navigation because its behind the whole thing and its gonna cost my 110 dollars for him to take out the navigation and it would take about 2 hours to get the serial number so he can get the code for my radio... is there any other way i can get my radio to work i drove my car around for 2 days now without any music.. and it sux if anyone could help me with this problem it would be great!
