Dvd players is a Boss audio dvd2000t(now is model# dvd2800t) about $125-$150 LCD screens, the 5.6 is a Tecview that I bought locally to save on S&h for $130.00 The 7" is from power accustic It cost me $259.00 the wireless headphones are also fro Boss audio they came with a transmitter and two head sets and cost me $65.00 Other parts consist of a video distribution/amplifier and a 12volt to 9 volt converter to power it that I bought at radio shack and it has one set of a/v inputs with 4 set of a/v outputs both together were about $60.00... I found that you can connect the line level output(audio rca output) from the dvd player direcctly to the AUX input on the stock radio. there are five wire on the back of the plug I forget the wire color code but they are Left+, Right+, common ground, and they last two if you connect them together this will ingage the AUX input on the radio, no need to disconnect them becuase you just have to push the FM, AM, DISC button to switch it off! all parts except the ones that came from radio shack and the 5.6 LCD came from The Wholesale House they are a wholesale distibutor they are on the inter net but only do sale over the phone and you have to have a Tax ID.
