My navigation stopped storing recent entries. I thought i would erase the ones i had, maybe it was full. I had Onstar upload a new destination, after getting there and turning off the vehicle i thought it would be ok. Got back in the vehicle and all the previous destinations that i erased were there again and nothing else. I also found that every time i start the car the same song from the HDD starts, no matter what i left off listening to when i shut the vehicle off. I have had the vehicle 1 year. Anyone else have this problem???
