The 2005 Ford Explorer sport trac doesn't have an aux input. You will come into difficulties with the sound. This might be from the stereo's speakers or a phone that is connected to the vehicle. Whatever the source, You will need to have these issues fixed pronto. If the problems are from the stereo's speakers, it could be static sounds, randomly turns off, a loose wire, or a blown fuse. If the problems are coming from the phone, it could be that the software won't update, the device will not sync with the vehicle, the phone's battery is almost dead, or an object is blocking the signal.
