I have a backup camera installed and i constantly get errors from SD saying that the camera is not configured, it works about 50% of the time and when i get the error it no longer works. The only solution is to toggle fullscreen or restart SD, but toggling full screen causes the music to be muted. Is this backup camera error going to be fixed or should i just forget about my $200 investment in a camera? Is the store willing to give me a refund?
