Matteo Parrucci an me upgraded all the collective.geo.* packages to work in Plone 5 during the ploneconf sprint in 2015. I remember it was all working nicely.
There is still a issue with the test-setup of collective.geo.bundle (https://github.com/collective/collective.geo.bundle/pull/35) which I have no time resolving right now. If you have a specific problem ("seems not working" ist not very detailed...) please create a issue in https://github.com/collective/collective.geo.bundle/issues
