Hi all i'm new on here as of today

 

As above really!

Are you sure it doesnt turn off?......or does it take 2 minutes to turn off?

hi i had the same sort of problem with my xsara picasso i took it to a dealership and they said it was a common problem that citroen don't know how to resolve but if you acounter the problem just find your battery disconect it and wait around 20seconds for all the current to drain out of the system , then just turn the ignition on and the problem should be over ! . there is only one problem with doing this, by dfisconectiing the power all of your radio presettings may be lost and the time and date will go back to 00 00 0000 . hope this helps the matter if not it may be a technical falt with your radio system

Hi Be interested to know if this does work, I have my doubts.

I tried to fit a Blaupunkt Hamburg radio/cd/bluetooth unit into my 2001 (old style) Berlingo, but it did a similar thing. When the ignition (from accessory or ignition position) was switched off, the radio stayed on, for 15-30 seconds (see "off timer", later) it went off, then a few seconds later, came back on, then off, then on, and continued on doing this. If I switched the radio off before switching off the ignition (from accessory or ignition position), the radio stayed off, BUT, listen carefully, and I could hear a relay in the fuse box near the OBD socket below the steering column pulsing on and off every 10-15 seconds. This radio has an "off timer" in its menu. This can be set between 15-30 seconds and so sets that initial period mentioned earlier until the radio goes off. This function cannot be disabled.

I contacted Citroen, Blaupunkt and a couple of others, and got this picture. The Berlingo (and other newish cars) have a multiplexed electronic control system (the BSI in the Berlingo). This radio, and other similar radios that have microprocessors, are not compatible with multiplexed cars, and can clash with some of the cars electronic controls, and vice versa (one person even suggested it could trigger an airbag !!!!???? ) without a special insallation. I have yet to find out what that "special installation" is. I will post an answer when I get it.

ps, I work with electronics for a living!!

2 of the wires in the radio harness will be carrying the data signal, these wires are in turn connected to the instrument panel, BSI and Radio. depending on the spec and type of vehicle there maybe other components daisy chained into this circuit, but for the benefit of the radio we will stick with just the instrument panel & BSI today.

 

Each of the data wires carries a data signal (well they would), one being a mirror image of the other. if you short these wires together not only will the radio stop functioning, it will also cause a problem with other components daisy chained into the circuit. If you short circuit one wire the system may work in a downgraded mode. It can tell if a data wire is broken/shorted because they give a mirror image signal of each other.

 

So what happens if you shove 12volts down the wire.......well anything else connected to the wire will get a little bit excited, possibly followed by the smell of burning....the data wires arnt fused!

 

So why doesnt your radio work......are the original data wires connecting to a pin on your new radio that they shouldnt be? i would identify the data wires and make sure they are isolated from other electrical connections...see if it then works, obviously it would be helpful to ensure you have voltage/earths at the correct pins before you do this.

 

tell us how you get on.

Hi, I checked the connections to both plugs with both instruction books before connecting, but now I will look at the plugs themselves to see if there are any extra wires not mentioned in the Berlingos handbook. If there is, they may be the BSI wires. Let you know later.

By the way, I removed the Blaupunkt and put back the original Citroen/Philips as soon as I realised all was not well. The car functions as normal, so I have not done any harm.

Bytheway2, I know its not directly for this thread, but it might be related. I have only had the Berlingo (its a 2001 Multispace 1.6 petrol) for 3 months. When I first got it the airbag light was flashing and some segments of the clock and odometer flash in time with the clocks dot. The airbag light cleared when I set the clock to the correct time, but the display segments continue to flash, odd! The service spanner has now come on at 6000 miles to go !!

Hi, Found out why! I checked the cars wiring, and compared it to the handbook. It is different. I think it is because the handbook is not the right one for this car. My car is a 1.6 petrol, 2001, but the book does not show the 1.6, it shows the 1.1, 1.4 and 1.8 petrol, and early diesels, so the connections shown are for standard ISO which is before my car. My car has the permanent 12v going to pin 7, and the accessory 12v going to pin 4. The connections shown with the Blaupunkt and the Citroen handbook is permanent 12v to pin 4, and accessory 12v to pin 7. So I removed pins 1 & 2, the BSI data lines, insulated and tied them back and swapped pins 4 & 7 , hey presto, it works !! It is a bit fiddly but with careful manipulation with a safety pin in opposite the wire you can remove the pins from the plug without damage, and fit them back in the new places. First remove a yellow locking bar from the side of the plug, it looks like a tiny yellow blob of paint.

At first I thought that there may be an adaptor to match them, but when I started looking, I could not find an exact match, and they all started around £14 for 2 cheap looking plugs and 8 short bits of wire! (Halfr---ds!), one type was £30 because it was for a Sony. :blink: Robbers !!

Switching on and off is still a bit odd, due to the way the accessory position in the car goes on and off! With the radio on, remove key, after 30 seconds or when you lock the car, plus Blaupunkt off timer setting (see previous post), it goes off. When you unlock the car and open the drivers door (no other door), the radio comes on!! This is because the accessory positon is controlled by the BSI current sensing, as well as the key, and goes off 30 seconds after the key is removed, if something is still active. The BSI senses a current requirement when the drivers door is opened, because as the radio is still set to on, and switches the accessory on.

Switch the radio off before you remove the key, the BSI senses no current requirement when you remove the key, the accessory supply goes straight off, and all is normal.

I wondered why the BSI data went to the radio, it must be to make the radio switching go with the key.

Did you know that if the ignition is left on without the engine running, it goes off after 5 minutes?

Simple fix, leave the yellow wire connected as normal and run in a new wire from the cigarette lighter, the ash tray and the panel next to it just pop out to give you access. I strongly recommend that you put an inline fuse from the lighter to the radio.

 

The cigarette is not on the bus and will provide a good clean source of 12v.

it sounds like both the red wire and the yellow wire are both constant live, one is supposed to go to the ignition live so when you turn off the ignition it turns off the unit,

i had the same issue and mine, so i swapped the red/yellow wire and this sorted the issue, but in my old car swapping them over made the head unit lose its memory so swapped them the other way and this also solved the problem, have you got the correct iso adaptor? they are about £20.00 to buy and the are stereo specific by car,

ie pioneer/citroen or kenwood citroen, the one i used is made by a company called connect 2 and was £19.99 plus pnp off ebay, it even has built in stalk control adaptor and it works well,

just doesnt connect to the head up display in the center of the dash,

 

hope this helps

I guys

 

Newbie here.

 

I joined purely because of this issue. I have a Berlingo as a second car and have been scratching my head over the stereo since I installed it. How could the original work and my Sony want to come on when I open a door and turn off a magical time later. Had got to the point of finding another 12v switched source.

The Berlingo is great but there's some weird logic in there.

I could not find a way of controlling an aftermarket radio sensibly from the ignition key so gave up and returned the original radio/cassette. That works ok but even that has one quirk! its a Citroen!! Turn the key to position 1, and the radio will come on, if it was on last time you switched the ignition off. Carry on to the starting position, and sometimes the radio goes off or sometimes the radio stays on when the starter is turning over. Its all down to the BSI !!!! By the way, Custardavenger, and anyone else, BE VERY CAREFUL NOT TO CONNECT PINS 1 AND 2 (black/white and red/white)TO ANY POWER OR EARTH, YOU CAN BLOW THE BSI, VERY EXPENSIVE! Custardavenger: check these pins on your Sony (Sony are also a law unto themselves), and for odd on/off, read my previous post
