Isimple aux input with usb was installed on 2009. Since then the radio seek function no longer works properly. Everytime you hit seek it just goes up by two even if its pure static. Example: your on 93.1 you hot seek up it goes to 93.3 which is pure static. Its as if the radio thinks EVERY station is giving a signal. This happens when the switch for the isimple is in the off position.
