BMW Navigator IV Issues

Does anyone have experience of the following problem.

BMW Navigator IV works quite will in standard cradles but when placing into the standard cradle of a GSA 1200 2014 or later, the Navigator works perfectly until ‘ignition on’. As soon as ignition on, the screen starts flickering and fading and eventually switches off.

I’ve tried many things but nothing has fixed the issue yet.

Thanks

This isn’t an OpenStreetMap problem?
