I have an 02 WRX the 6 disk broke (Cd's wont play) so I bought a flip down screen DVD/CD player from Fry's DP Video cheap unit I know. The problem is that when I start the car it looses all the presets. At first it was only every once in a while now its every time. I have taken the radio back and got another one and same prob. I used a wiring kit and double checked that it is OK. Sometimes when the key is off the radio will light up but only if it lost the presets and i turn the car right off. I did some testing and I have good voltage with key on or when running like 13.8v to 14.6v but as the starter is turning it drop as low as 7v and when it stays above 9v i don't lose any presets. The battery is only about 18 months old. I don't want to buy another one without ruling out any other problems or issues first.
