Hello, I have a Pumpkin Android 4.4 Navi / Radio with bazaar soft IGO plan.

My problem is that all of a sudden I have a black screen during navigation:

15471d1452791932 igo schwarzer bildschirm waehrend der navigation 20160114 144730


The navigation continues (voice and display top left), and when I go to finish bottom right I come again on the map.
