Satnav And Computer Problems On C5

[sarrybaldy]

Hi all.

I have an 02 C5 Estate 2.2 Auto Exclusive.

It has the Built in Sat Nav and colour screen along with Traffic master.

 

Traffic master never seems to work, thegreen LED never lights up, but I can get a response out of the system and switch between auto and manual by pressing the button.

 

I regularly lose the mapping function of the satnav which I improved by just running a cleaning disc in the CD unit.

However, now the whole system regularly crashes.

The screen blanks and I lose all control of the Satnav, the CD unit and autochanger.

The computer however rmemebers all the settings and will display the correct trip data when the unit finally boots up again.

 

Usually if the unit goes down, I have to leave the car at least overnight before it will boot again.

 

Any ideas????

I have the same problem with my Traffic Master. I suspect the aerial is duff, as it appears to have rusted into place and will not unscrew. GPS coverage for Sat Nav is not ideal either, but the Sat Nav works moderately well. I may try and run an independent aerial for Traffic Master to see if this fixes the problem.

 

I think (but this conjecture) that the software you have running your Sat Nav is corrupt. According to the Citroen manual, the car came with 2 CDs, one with the software and the other with the maps. If you have this software, you might want to try reloading it. However, there is a risk to this. It might stop working all together.

 

The problem with many second/third owner C5s is that all this documentation/CDs/Security card has either been lost or sold separate from the car. It took me a while to get the correct manual for the car (2002 C5 2.2 SE) as the previous owner had simply bought one for a newer car, which was mostly incorrect for smaller driving controls.

 

The only place to get a commercially available manual is in France, in French.

Thanks for the reply.

Luckily I've got almost all the documentation , books and the CDs.

Next step is to try and re-install the software then!!

I'll let you know how it goes!

Tried all sorts and nothing worked.

 

As I posted elsewhre, Kent Elms Citroen have diagnosed the ECU, apparently 3 parts to the system.

ECU, CD player where the software CDs load and the screen.

New ECU is £850+vat+fitting.

Currently looking at Ebay also the local garage has a man who repairs ECUs for "a couple of hundred quid"!! So might yet go that route.

 

By the way, new aerial and base, fitted is almost exaclty £100.

 

Anyone know exactly where the SatNav ECU is hidden?????

Did you sort your problem out? I have had the same issue for a year now
