I have an Ouhua DVD navigation, and now DVD does not read the disc, has been changed once bald, and feel very costly. Now even more than U disk song when there will be continuous flashing refresh the song, do not read the song, sometimes heard half of the problem, not very stable, and the interface is very cottage unfriendly. If you plug in the memory card will be unable to control the sound, and each switch plug card must re-select the song, very troublesome. I am looking for a solution to the loss of the smallest music effects, such as re-install a DVD player can read the card, or amplifier, or with the original DVD audio input interface plug in MP3, so the effect will not be discounted A more optimized solution.
You are a problem with the machine, it is recommended to repair it. Do not read the DVD read CD can be probably the problem of bald. Read the card, read U disk with the bald is not related, I think it is a circuit problem.
