Good evening! Last week we finally picked up our C5 AC (Benzin, Shine, White Pearlwood). A great car! very comfortable, quiet, equipment Top, 8AT Top. We are very satisfied. unfortunately we now have a problem with the update. Got notification from My Citroen Handy APP that there is update for vehicle data (version 31.09.46.62_NAC-r0-04.07.19, the current version is 31.08.05.86_NAC-r0). I then installed the application Citroen Update in the laptop (Windows 10) and the update files downloaded and pushed into a USB stick like the manual. But shows in the car “version not compatible with hardware”, then tried with 5 different USB stick, all are FAT32 format. always does not work. Did the files also download from Email Link and spit into USB, does not work either. On the Internet I have seen many similar problem…. What can I do? Should I drive to workshop? another question for Navi card, the version the map is from 29.04.2018, there is no update for map material. Is normal? do you also have the map from 29.04.2018? many thanks in advance.
