We need to know if your Sat Nav is RT2, RT3 or RT4. I only know about RT2 as that is what my C5 has.

 

Please can you tell us which year and trim level.

 

If you are talking about a 2002 C5 Exclusive, which has a Radio/CD, a changer AND a separate CD-ROM drive for the Sat Nav in the extreme right hand compartment to the right of the steering wheel, then I believe (not really had cause to do anything else) that the CD-ROM drive and ECU are the same box.

 

I expect some of the top guys to correct this.

 

If I were you, I would check that the backlight bulbs to the screen are working first.

 

If your Sat Nav is RT2, do you have any map CDs for it? Do you have the original software on the CD for it?

 

When you start the car does a little red light illuminate on the front of said CD drive, if it has a CD in it?

 

It's a risk but you could unplug the CD-ROM/ECU. After all, It's an optional extra. However, it does interact considerably with the screen. At your own risk.

 

Do not EVER disconnect the battery when the red light is still on, as it indicates disc activity. This is a good way (rumoured anyway) to kill the Sat Nav.

thanks for your intererest.my car is a 2001 v6 exclusive se so the sat nav was o e. it all worked well when I bought the car last year then became intermittent and then stopped working completely. I dont know what model it is because I dont know how to remove the unit from the glove box.the haynes maunual doesnt cover sat nav.the red power light comes on when the ignition is turned on.a club member had the same problem as written in 2007 and the garage told him it was the ecu.citroen quoted £850 plus fitting!!!!!!!there is a unit on sale onEbay but doesnt look like the unit in the car

You don't need to remove the unit. I have described a system (RT2) where the CD drive for the Sat Nav is separate from the Radio/CD. With RT3 or RT4 the Sat Nav CDs or DVDs are placed in the main Radio/CD player. With RT2 they are separate and I would imagine from what you say that's the system you have.

 

Is there a CD in the drive? Can you hear anything like the drive working? Can you eject the CD? Can you swap it out?

 

Do you have the original software? You could try reloading it if you have.

 

Have you ever disconnected the battery without checking the Sat Nav CD drive has stopped? If so it is dead.
