	If the rest of the car turns on then you got some botched wiring in that car fella :lol:

	Right sorted :D didnt relise you had to leave the yellow wire unconnected once you bridge the others So with it like this it works although i have to manually swtich it on and off so im going to look into what is wrong with the accesory position on my ignition anyway Unless the front pannel is removed it stays in standby mode so i am going to put a switch in the live wire and put it in the ashtray so it can be fully switched off :) Anyway job done for the moment thanks guys :thumbs: [Edited on 29-07-2007 by gavin18787]

	Thats what I have tried already rich but it makes all the dash lights come on and the fan etc as well the whole time :boggle:

	And by that i mean

	This could still be a fuse.... but the more common problem is the ignition barrel contacts going wrong. If you swapped the yellow and red wires round and it saves the setting...... just run a wire between those two wires and it will all work fine :)

Im sorry, Ive lost what your trying to do now :( [Edited on 28-07-2007 by pow] I tried taking a live from my power cable that goes to my amp. This made the headunit come on but also all the dash lights and fan etc :boggle: I think something is fucked with the cars wiring................ Basically i want my headunit so that i can listen to it without the engine running :)

	Slight update, ive managed to get the unit to save its settings by swapping over the red and yellow wires. So if its saving settings surly this means there must be a constant live :boggle: So its leading me to belive its the accesory switch on the ignition and the remote wire that may be the problem.......

	quote: Originally posted by pow If so, this is what you need to do: Been out and tried this, not anygood as it makes all of the lights come on on the dash and fan run etc even when the key isnt in the ignition :o I tried to use this to find which wire has the perminant live. Couldnt find any at all but im not 100% sure if i was using it correctly as there are lots of switches and symbals :boggle: Any help would be apriciated as i want to get this solved this weekend :thumbs: [Edited on 28-07-2007 by gavin18787]
gavin18787	posted on 27th Jul 07 at 17:21
	Going to try the wiring as suggested to see if i can get it constantly live and manually switch it on and off. As i think the problem may lie with the swtich on the ignition as nothing seems to happen when it is turned the first click. Is there anyway i can test it?
gavin18787	posted on 26th Jul 07 at 17:08
	interior light is fine and i belive it is storing the settings ok as it was still tuned to radio one when i got in it today. Also With my old headunit (a JVC one) it had two positions for the fuse. I had the same problem until I swtiched the fuse to the other position. So some form of perminant live must be operational :boggle: What ever moving the fuse changes is what i need to change, however it wasnt ideal as the headunit was always live until you switched it off (bad if you forget :o )
Richie	posted on 26th Jul 07 at 15:42
	pow...... that would still only work when the ignition is on. The problem is with his permanent live... its totally dead Your settings shouldnt be saving either if im correct? Does you interior light work ok?
pow	posted on 26th Jul 07 at 14:44
	If so, this is what you need to do:
pow	posted on 26th Jul 07 at 14:39
	But you want the headunit to work with the key out of the ignition, yes?
gavin18787	posted on 26th Jul 07 at 06:36
	and yer its a corsa
gavin18787	posted on 26th Jul 07 at 06:36
	quote: Originally posted by Richie Is this a corsa? Sounds like a blown fuse in the fusebox for the permanent live. This may explain why key has to be turned all the way round for anything to happen, any idea which fuse this is mate? :)

	You need to connect both the yellow and red wires to the red wire :) Means the headunit has always got a live feed!
gavin18787	posted on 25th Jul 07 at 19:32
	Installed my new headunit today and i cant get it to work without the engine running. I solved the problem on my old headunit by putting the fuse in its other position but this one only has one place for the fuse. I also swapped the red and yellow wires as shown but that hasent worked either :( Please help :boggle: :wave:
