Buenas tardes
Por favor necesitaria saber si hay alguna actualizacion para un DS 7 Croosbarck año 2019 Diesel manual
There’s no need for that. The 2019 manual is still valid for cars built in 2019. Joke 
Generally, you can’t do software update by yourself, so it’s best to ask your local DS dealership.
Hola;
Gracias Andres_PL consultare a un servicio de DS antes de hacer nada.

The only DIY is entertainment/maps update you have is in the DS_update application on PC/MAC
