I just bought a 4" LCD screen and a TV Tuner. The screen is from partsexpress.com, not sure about the model #...and the tuner is a XOVision XT-5000N. I'm tryin to get this thing to work, at least so I can test it outside of my car.

The screen has a set of power wires that I hooked up to the + and - of a spare car battery I have. It also has a jack runnin out w/ 2 RCA jacks on the end. The RCA jacks get plugged into the tuner, but there's a "A/V - 1 (NAVIGATION)" set of plugs and a "A/V - 2 INPUT" set....

The wiring harness for the tuner is as follows:

white - FM TX Antenna
black - ground (-)
red - Acc B+
blue - Break Terminal (-)
yellow - Vcc B+

Here's my questions:
- Which A/V inputs do I plug the dvd player's RCA's into?
- What's the white and blue wire for?

I wanna make sure I didn't buy a busted screen and tuner....

 

Just put it in your car and star wiring stuff up. It wires up just like a cd player. ONe power, one accessory, one ground. A 4" screen is really small and is going to be super difficult to see comfortably. I would had gone bigger IMO.

If the wiring isnt right, you're not going to hurt anything (I'm sure you can get the red, yellow and black right). Leave the 2 off that you dont know what they do. They seem to be something that can be used for a factory navigation system.

Is it a headrest monitor?

 

I believe it was, but now it's got the casing removed. I got it all figured out. Aside from it having a switched + AND - to turn it on *jeez*, the battery I was using to test it apparently didn't have a good charge, so I thought I was screwin up the wiring. Thanks!
