We recently bought a Clarion NZ500 nav receiver along with modules for HD radio and Sirius for my wife's car. Seems to be working except for one thing. Most of the time in the car she listens to a particular FM station. When she turns off the car, comes back later and starts it up, the radio comes up on a different FM station. It's driving her nuts. Is this probably an issue with some kind of mode we haven't noticed or figured out? Or could it be a defect?
