How do i connect my dvd to my car power supply?

What would cause a new car indash DVD player to not power up correctly. The unit recieves power, but...?

• It needs to be reset in order for it to light up. It is wired correctly. Aside from being the unit itself that may not be working correctly, there is a fuse that is found on the yellow battery wire. The fuse seems fine, and the previous indash player worked fine. This is basically what happens: 1. I turn on the car, but the unit does not light up. 2. I hit reset. 3. The unit lights up. 4. I turn off the car. 5. If I turn on the car again, the unit does not light up. 6. I need to hit reset for the unit to turn on. The unit is a model TS-393 (also known as DV-393) made by Avatar Electronics Ltd. You can find the unit on eBay be those model numbers.

• Answer:

  It sounds as though your 12 volt accessory (typically a red wire) is not connected properly. This wire is what signals the unit to turn on and off with the vehicle. Either that, or the 12 volt constant wire (typically yellow) is connected to a 12 volt swithed power source. Double check all your wiring - if all wiring is confirmed correct, there may be a problem within the unit itself, but it is impossible to tell with the little information you provided. Additionally, there are certain vehicles (you did not include the make and model of yours) that do not have a 12 volt switched power source behind the radio.
