I just bought a Clarion VRX935VD from one of my friends. He did tell me that it has problems playing dvd's/cd's. When I insert a dvd/cd, it says ERROR 6. I looked in the manual, and it says that ERROR 6 means that the dvd/cd was put in upside down. So I flipped it over and it still says ERROR 6. What going on here? Thanks
Here's the manual...page 63 is the ERROR page.
