Hello

There is very little information about the GPS antenna.

But to make a start at one end, remove the radio and find the GPS connector on there.

You can try a temporary GPS antenna to prove/disprove that, which can save time, all assuming you can find a GPS antenna with the correct connector. Luckily they seem to be standard fittings.

There are several radio options fitted to the A51 Citroen C3 so the removal is similar, but not identical to the others. But the same idea applies, just get the right radio removal keys and use those to unlock the stereo. You can then remove the stereo to find the connectors on the rear.

thanks mate, so its not behind the screen but behind the actual radio.

Yes, there isn't much behind the screen. Its just a screen.

All the work is done by the radio, except for some with a sim card/data device in the dashboard area.

It will probably be easier to remove the radio and have a look at the stickers. It's not so easy to check by VIN at the moment. Citroen restrict access quite regularly
