Hello all, newbie here, have just purchased a 2004 range rover L322 4.4 v8 vogue and I love it, however... It does have a little issue, the Sat nav screen had been smashed by the previous owner (naughty child having a tantrum) the screen still powered up and the back light was very bright, I bought a replacement head unit from flebay and installed this today but sadly the screen is completely blank, I can see a slight change in the contrast when I turn on the ignition, but no picture? I tried removing fuse 49 for 20 mins and still no change, I then checked the nav computer in the boot and it when I press the eject button the power light comes on but there doesn't appear to be any cd in it... Could this cause the screen to not load? Everything in the rear compartment is perfectly dry and looks in good order so I am really stumped, the radio works and the buttons on the head unit work I just can't see what I am doing! Any help would be much appreciated. Many thanks Pete
