the screen cost me $179 becuz i opted for the one with head phone jack built in, idk why tho itll never be used... u can get it without for $149, it has a tv tuner but it uses an external video source... such as an xbox/dvd player. U can plug an antenna into it and get radio transmitted tv

u can tap into the existing wiring or u could run ur own wire off the battery if u wanted... mines wired so the screen turns off when the cars off, but the blue LED's stay on 24/7, they're just LED's tho so its not too big of a deal...

Stuff: Xbox, 7inch tft screen, 2 12inch infinity 1242w's, poweracoustic amp,pioneer HU, Tokico HP struts/springs, buddy club p1 perforance II plus 17inch wheels
