@M-Schrijver, many thanks for your hint!

In the past I always changed volume for Telphone,
but this is not the Telephone volume in general but Telephone CALLS!

The right volume configuration for the Navi is "Musik" and than there is "Background Musik" while Intercom. This is why the Navigation volume was reduced during Intercom.
I increased "Background Musik" and everything is perfekt.

Many thanks again for the possibility to discuss ans finally solving the issue I already have for years now.
Really happy! THANKS!
