I recently installed a new battery in my daughter's 2009 Kia Rio. Afterwards, the factory installed radio (bluetooth option) refused to turn on. The battery was installed correctly - i.E. Terminals not crossed. Audio fuse checks out OK. What could be causing the problem? I've been told that some Kia radios must have a re-set code entered after power is interupted but how can this be done if will not activate.
