Carplay & onboard navigation in parallel

My onboard navigation can show the maps & routes in the driver display and includes things like which lane to use.
ABRP carpplay can run at the same time on the media center screen.

However: When I start an ABRP route the onboard navigation system switches off and only tells me that carplay navigation is active.

I’d like to use both in parallel !

Why does ABRP tell the car has an active route? Can this be turned off / made optional?
