After several failed attempts, I decided to install the iGO Primo from Honda recommended by Boki_Srb and the route problem was solved. It no longer produces straight line errors south of France. Now it works fine! I find it strange, the program indicates the exactly same version and the same configuration files, only the PRIMO executable has a bug and the other does not.
Now I can drive in peace in the valleys of death!
Thank you friends!!
