jysi, do you have such files for Ramses?

Thanks jysi.
The Mercedes part number appears to match the Hermes version.
All of them can support GSM (2G), UMTS (3G) or LTE (4G), depending on the destination market.

An example of a Hermes 1.0 inside with a green USB connector going to the multimedia unit. In this case, data transfer between the multimedia unit and Hermes is carried out via USB. Often found when entry head unit is built in (code 522 for W213 E-Class).
Another type of communication is via WLAN (Comand Online or Audio 20 with code 531 or 506 for W213 E-Class).

Ok, with this guide, is it possible to change the country so that Hermes can call emergency services in another country, or is it not possible? I am looking for information on how to do this in Xentry. Thank you.

I know this is an old question, but Xentry has a feature that allows you to change it without any code.

I have already managed to change it, with Xentry 12.2023 all that remains is to select the country, anyway thank you very much.
