I want to hack my dvd player for my nissan quest 2007

you said CAN , i bet you meant CAN'T or CAN NOT. right?
the AUX port is just a line input, analog audio input,
it dont know MP3 .
it only amplies the analog audio found there.
you connect any device, to AUX. push play on the device.
then put car radio in to AUX input mode and play. the audio.
that is all there is to it.
the external device does all the heavy lifting, reading a file, and decoding it (mp3 decode) and then sends raw analog audio out.

the cable is sold and radioshack, or walfart or many other stores,
Target, most MP3 players, come with this cable,
they use mini phone plugs, stereo, type,. (3 contacts)

DVD REGION FREE & BLUE-RAY REGION FREE
To change the Region code on your DVD player, open Control Panel - System - Hardware - Device manager, and click on DVD/CD ROM drives, then right click on the DVD drive and click Properties then click on DVD Region.
You can enter a new region and it also shows you how many changes have been made.
NOTE you can make only 4 changes and the player will lock permanently on the 4th change.
If you want to play DVDs from any region you maybe able to upgrade the firmware to make it region free BUT if you make a mistake or installed the wrong firmware the player will be a piece of junk.
The best solution to make the player region free is to install a piece of software (Passkey for DVD) that allows you to play DVDs from any region and Passkey for Blu-ray that allows you to play Blu-rays from any region. There are several available on the Internet but my favourite is DVD-Region Free From: -
www.dvdfab.com/products,free.htm

If it is the base model (S or SE) then it has disc front and drum rear brakes, if it is the SL then it has four wheel disc brakes.

Samsung DVD-V8500K
1. The player should be powered on, the tray closed without any disc inside, the logo "DVD Video Samsung" visble on screen and the message No Disc must have already appeared.
2. Press the "Subtitle" key on the remote - "No Disc" should disappear.
3. Using the remote control, key in the code
"5, 3, 8, 1, 4"
4. A number should appear - this is the player's region number that was last programmed.
5. Press the number of the region you require, or 9 for region-free.
6. Press the "Subtitle" key on the remote - region number should disappear.
7. Press Standby on the remote control.
NOTE:
Origin of this player is Region 5 so it`s a default setting
If code "5, 3, 8, 1, 4" doesnt work try this codes:
Region 1 - 2, 9, 3, 3, 4
Region 2 - 3, 8, 7, 6, 7
Region 3 - 5, 6, 7, 3, 2
Region 4 - 7, 6, 8, 8, 4
Region 5 - 5, 3, 8, 1, 4
Region 6 - 2, 4, 4, 6, 2

Hi I live in Australia and added this model.



acknowledging: Region code hack posted by ZoidsGodzilla, November 22 2006: for the Samsung DVD-V5600

1. Press the DVD button on your remote (the Samsung logo appears)
2. Press the SUBTITLE button on your remote
3. With your remote enter the code: 76884
4. The current region is displayed on the top left corner of the screen. (e.g. 4)
5. Press 9 on your remote (Region free)
6. Again press the SUBTITLE button on your remote
7. Enjoy the Region free player

If your player is NOT Region 4 by default then you will need to Substitute the Numbers in Step 3 with the ones Below.

Region codes:
RC 1: 2, 9, 3, 3, 4
RC 2: 3, 8, 7, 6, 7 (or 5, 7, 5, 3, 8 )
RC 3: 5, 6, 7, 3, 2
RC 4: 7, 6, 8, 8, 4
RC 5: 5, 3, 8, 1, 4
RC 6: 2, 4, 4, 6, 2

For Example if your Player was Purchased in the usa ( Which is Region 1) then Step 3 would read :-

3. With your remote enter the code: 129334

Have Fun :0)

I picked up a LG DV276 DVD Player here in Australia but I am from the United States so I own region 1 DVDs. I unlocked my new player by instead 1. Open the tray. 2. Press 0 0 0 0 on the remote and a Menu will appear. 3. Press 0 for region free. 4. Press pause and power off.

I can play everything now, Aussie and US DVDs. Thanks LJ66.
