RT6 map 2021 to map 2019 possible?

GPS RT6


Bonjour,

j'ai actuellement la cartographie 2021 mais vu que le système TMC ne fonctionne plus avec (il semblerait que oui avec les anciennes versions) je souhaiterais revenir à une cartographie 2019.
Est-ce possible?
Comment faire?

Merci à vous.


Hello,

I currently have the 2021 map but since the TMC system no longer works with it (it seems so with the old versions) I would like to go back to a 2019 map.
Is it possible?
How to do?

Thank you.

TMC service isn't free in some countries, and it's encrypted. To decrypt it you need a decryption table that is (or not/no longer) delivered with cartography.
End of the PSA/ViaMichelin contract = deletion of the table on map update = no longer possible to decrypt the ViaMichelin TMC.

Thank you for your answer that's why I would like to go back to a 2019 mapping because the TMC still works it seems to me.

Install older maps is possible, but in your case, that wouldn't make TMC works in France. That was possible for some months, but now certificates are revoked. No data from Via Michelin.

OK, understood.
Thank you for your answers.
