Another head unit thread...
#1
Music 
Hi All,

I'm new to the Berlingo world Big Grin and just in the process of preparing to transfer my audio gear from my old Volvo to my recently purchased 2003 Berlingo.

First step is to get my head unit and sub/speaker wiring installed but I cannot confirm what harness adapter I need to get my head unit to talk to my stalk controls. Also I want to find out if there is an adapter available that will get both my stalk controls and dash display working.

My Alpine head unit is compatible with steering controls and dash displays but information regarding such adapters is a minefield. I have spent hours of this weekend researching and I still feel like I'm no closer to an answer. Obviously I have trawled this forum unfortunately to no avail. It seems like the vehicle being CAN-BUS equipped could help quite a lot but cannot find a way to confirm this either. I understand 2003 may be a little early for CAN-BUS?

Has anybody managed to successfully get their Alpine head unit to work with stalk controls (stalk not on steering wheel) and the dash display?

2003 will almost certainly be Vanbus not Canbus. The tech support people at Connects2 were really helpful when I was thinking along the same lines. The wiring for the radio is shown in the drivers handbook which is on here somewhere, pinouts are also online. IIRC, you can get a stalk control adapter but the centre display will only work with the citroen radio.

Thanks for the heads up on the handbook, found it here.

My suspicion was that I'd have to settle for stalk control without display but there may be hope yet!

Over the weekend I sent a few emails to various audio suppliers including Connects2 and even Alpine themselves. The only response I've had so far is from caraudiodirect who have advised that Alpine's own APF-D100PS will make the stalk and display work in the Berlingo. After I confirmed the Citroen head unit model number (RC260) they were able to confirm this adapter will do the trick:

I've found various videos and threads from the guys in Europe getting this adapter to work in almost everything apart from a Berlingo so this could be a first!

I'll order one up and report back...

Hi all,

So I finally got my hands on the Alpine APF-D100PS adapter harness but I have an issue which I need help with.

Installed it in 5 mins, very simple job. The problem is while the ignition is on, the head unit switches on and off continuously at about 3 second intervals. The dash display says alpine and for the split second the head unit is on and able to respond the stalk controls do work. If I switch the ignition off I can manually turn the head unit on with the head units power button and it will stay powered up and work fine without the use of the dash display and stalk controls as they are powered down.

Does anybody have any clues what might be the cause?

Does the power to the head unit also switch on/off at the same interval? Looking at the radio wiring in the handbook there are 2 power feeds, one is switched & the other permanent, just wondering if the car is pulsing the switched line?

I'll need to get the multimeter on it to confirm although the head unit works fine when the ignition is off.

Obviously when the ignition is off the dash display and stalk controls don't work, so I'm sure its something to do with those integrations causing trouble.

I've just heard back from Alpine and the first test they've asked me to do is to try the loom with the 'D' shaped plug (part of the Alpine loom) which connects the dash display disconnected to see if this stops the power cycles.

Will try this and test the +12v feed.

I took a look online and could not find any useful Alpine documents so it's good to know that they've been in touch. For the 12v test, it might be easier to use a 12v bulb if you have one to hand. I think you're probably right about the integration with the car if it's working fine with the ignition off but the 12v test on the switched feed will help establish that.
