(G) head unit backlight on constantly

Hey just bought a marea saloon 2.4jtd however i needed to replace the battery as the one that was in went flat and was completely the wrong size but my stero is now light, not actually playing anything as i need to get a radio code but just sitting there all light up, is there anything i can do about this?

Pull out the stereo and it should be written on top of the metal casing.

He has the code.. It's all lit up though. Even when its turned off.

got the code and that all works fine now but is still all lit up even though i have turned it off

If you can't get it off tomorrow ask Fast to remove it and reconnect the plugs on the rear. Maybe that will wake it up. Might be worth pm'ing Bulldog to see if he has a headunit going spare.

yeah was going to will see what they say before doing anything

got some head units
some with steering wheel control
black - beige foc to good homes
can leave in newcastle some where

low and behold everything is fine with it now havent done anything execpt i disconnected the bat last night till this morning and it now all turns off when i turn the car off

I had a battery change recently and a similar thing happened to me. I noticed that the backlight and button lights would stay lit with the engine turned off after the change and this persisted for a few days. I then noticed the backlight flickering between bright and dim (I think it was probably the settings for headlights on and off) one lunchtime when driving. After this the light would go off some times when I turned off the ignition and not others, and now it's finally decided to switch off every time.

Another Fiat electrical "feature"?!

thats it exactly the fault i was having

I've linked this between the Marea and Bravo/brava forums as it seems to be a common issue between the models. Not heard of it before then suddenly we have about 5 cases within a week.

hmm, mine works fine, guess i'm getting what i deserve for installing a beauty of a pioneer headunit

OK - I visited the local Fiat dealer today having found and removed the relevant fuse (it was very helpful knowing that the central locking was on the same fuse). They put the fuse back in and say the backlight stayed off - they can't find any draw on the battery that shouldn't be there. But I know I wasn't imagining this (again helpful to know from all of you that I'm not going mad) - so I have to either decide to replace the head unit (learning the technical terms now) or just cross my fingers and hope this has gone away. Living in Edinburgh I hardly use the car, maybe once or twice a week for short journeys (which is probably why whatever is draining the battery gets the chance to completely flatten it). If anyone has any advice I'd be glad to hear from you - thanks.

well ive just been disconnecting my bat for the time being when i cant get it to stay off saves going round and locking all the doors lol but im going to get my head unit whipped out then going to take it to a repair shop (non-fiat who was recommended) so will let you all know how that goes

surely the cheapest option would be to remove a headunit from a scrapyard car. that will only cost £10, and the headunit code is easily found using the numerous free programs you can download online.
