C5 Replacment Advice

[CITROEN-NUTS]

Ok looks like the head unit in my C5 is on its way out as the FM tuner is messing about and from reading other threds it seems to be a known issue.

 

As such I looking to fit an aftermarket unit with maybe DVD screen for a rear camera and would like to know if anyone has had issues with the ISO multiplex adaptor (my car is a 2001 LX ) but most of the audio shops I've been to have advised to check with citroen.

 

Any advice form anyone whos fitted an aftermarket unit would be helpfull

 

Thanks

Hi

I fitted an aftermarket unit (Sony), but never got it to come on and off with the ignition - that requires specialist , and expensive additional kit that goes into the ISO connection line. The permanent feed actually switches off after a couple of minutes anyway, so no danger of draining the battery. Switching on and off manually is no problem really.

Connection to dashboard display and remote controls is more additional cost. Reckon on around £150 for extras if you want to totally replicate the functionality of the original, and check the radio you buy will do everything you want it to - some don't have remote connectivity. You will of course gain MP3 disc compatability and ipod connectivity, which can be an advantage.

Good luck

connecting to a switched live is easy enough and you would still need a permanent live to the radio memory ( the wiring on the aftermarket unit has 2 wires that are live red and yellow ) you need to connect the yellow to the red and red to yellow but you already knew that didn't you cough, if it doesn't come on with the ignition then you need to probe for a switched live and a permanent live and a multi meter is required for that but for it to work with the steering wheel controls a special adaptor is needed not sure if you can get one through halfords?

Not that simple! I tried every combination of the red and yellow - crossed, straight and merged. I got a permanent feed effect every time. When I spoke to a car radio installer, he advised I needed a "Can Buster" to communicate with the car's ECU.

This from Nexxia.co.uk....

 

IGNI-GEN

Modern vehicles that have Canbus Systems, do not have an ignition switched feed to the car radio. If installing a new radio, this can cause problems for the radio to work properly. This device can be fitted to create an ignition feed where one doesn't exist through sensing the Canbus signals from the vehicle.

 

 

Price £18.99

same with the Audi and when fitting an aftermarket radio you cant communicate with the ECU to do diagnostics as the radio is linked to the ECU for anti theft reasons, but that's for cars that are CAN bus orientated

 

can buster sounds good though
