Currently it turns on but the screen is black but backlit. The radio knob light goes on and off when pushed, the cassette eject works and so does the mpg data etc on the speedo display. Has it had it and therefore requires replacement?

It started after I removed the radio and sat nav fuses trying to reset to unit to fix an issue with no sound from the tv as well as unable to select the cd changer or radio functions. I had read that the units can be bricked if not enough time was left after it was powered up but it was left for over 15 mins which I assumed would be ok.

I did initally think it was just powering up and rebooting as the manual says that after a power disconnect it can take around 15 mins for the unit to be fully operational. I have left it for 20 mins now though and nothing has changed.

If i have bricked it, is it the tuner in the back that will require replacement or the unit in the dash? How does this also relate to the functions of the tv sound and radio as I guess I would have to replace it anyway if those weren't working from the start?

Thanks all

Thanks both but I think I'm screwed. Waited for the light to go out, removed fuse, 1hr wait and then tried it again. Can hear the unit in the back and in the dash power up when the fuse is inserted but screen stays all black (but backlit). Damn. And I had red about waiting for the red light to turn off before but totally forgot.

I've also checked all the connections and ejected the disk etc all to no avail.

So I am looking at a new unit or a reflash i suppose. Does anyone know a place I can get this done? I have searched but found no links.

Is there not a way to get everything else to function apart from nav facilities? I'll only use the tv and radio etc.


Surely this is quite a common problem as it'll do it everytime power is removed from the car minutes after it has been powered up?

Thanks. Do you know roughly what sort of price it would cost to reflash as it would probably be a lot easier to buy a second hand unit if its just going to be a case of pulling the old one and putting in the new. Or do you think this might jave compatability issues.

The connectors all seem in pretty ok and I didn't touch any of them after it was working good, pulled the fuses, put it back and then it was broken so I doubt it could be anything else. Which ones are prone though? I will yank the sat nav unit out and check the back ones later as I've only checked the ones on the tv tuner.

hi. You should be able to just disconnect the sat nav to restore all screen functions albeit in a rather ugly font. If you've already done this and you still get nothing on the screen then as has been said, you need to check all connections.

I know a guy who serviced my DVD in the boot for £99. I have a screen for sale also. Took it out of mine when I upgraded.

Woo hoo!! Disconnected the sat nav unit and got the screen working again. The graphics are just the same just without the sat nav option. Replugged in the sat nav unit on the off chance and pow, its all back working again!! Thanks guys.

Despite this I am still having the same issue as before I tried to fix it and subsequently broke it : No sound at all. I've checked all the connections in the boot and there doesn't seem any sign of corrosion. I've tried cd's, tapes, digi tv box but nothing comes out of the speakers at all unless its instructions from the sat nav itself or when using the parrot bluetooth system.

I suspect this has something to do a problem with the radio. Is this in the head unit or is it housed in one of the boxes in the boot? The radio seems to be stuck in MW band and none of the buttons seem to work. Only thing that ever changes is sometimes the radio display on the screen goes blank in all the boxes. Does anyone know what this could be?
