I have a 2004 chevy cavalier ls sport coupe on crutch field it asks if the car has RDS and onstar. How would i know of it has them or not?
Please help.
Look at your rearview mirror. See if it has an onstar button. If it does, then you have it. Your radio would have an rds decal on it.
Will anything happen if I order one without either and I do have lets say rds?
