I am double sorry.
One, I did not see your last change before.
Two, the software version don't ring a bell about whatever software is running.
The good news is that this is the very latest firmware on Peugeot/Citroën MyWay devices, that new that it is
not available on any forum yet. The bad (?) news is that it seems to have some extra security build in. Like backup sd card won't function anymore, you need the original that came with it.
The new release has this features (not confirmed however!):

I don't know if you know French, but the 'noms des rues' indicates TTS.
But it could be only for the more expensive unit, and not yours.
Concluded, I do not know how to help you.
But we have a forum for Citroën/Peugeot.
