hi all, after owning my 58 plate sri since jan, have done a few mods on car but no ICE yet (usually my first port of call in a new car) as i dont wanna screw with canbus. After looking at pics and reading into everything on here, i would like to upgrade my mono display (BID i think) and maybe drop a DVD player/sat nav/or just mp3 compatability once screen upgraded. But money does come into it as with everyone, does anyone have advice on changine all this? can i replace screen first? will new display be supported? not too concerned about dab but would be nice!
