I have a Espace IV, all work but the screen display the satelite reception in red, so when i put the good cd map don't display the position.
I check on the roof the litel antena is connected.
I's it a re localisation to make ?
relocation wont solve your red dish problem. antenna is most probably dead. install an aftermarket antenna with double sided tape for $10 on the dotted part of the front screen (top middle), take the wire under the roof lining and A pillar behind the gl glovebox. this is a quite common problem. factory aerial is too expensive and half a day to install and high risk to break some crappy plastic tabs...
