Is there a way to hide an attached geolocation layer or show 2 content types without beeing attached as geolocation layer

Can somebody give me a hint, how to hide an attached geolocation layer, or how two show 2 different content types on one map

I got a view with a first content type where the user can filter categories of markers (from a taxonomy).
To show a second content type i added a geolocation layer that is attached o the same view.

Problem:
When a user filters the first content type the second content type is always shown as well.
I like to give the user the possibilty to hide or show the second contenttype.

I tried several ways, for instance an exposed filter of the 2 content types, but this is not a solution.

Any hints and comments would be highly appreciated!
Thanks pidru
