New question / problem.

I was a happy user with CNEUNTU2016.20 on my Nexus 2013 WiFi v2 with Android 5.1.1.
This morning Google updated my Nexus to Android 6.0 and now Street Pilot stops working immediately after start-up.

What do I have to do in order to let in run OK again?
Is it a known problem?
Anybody?

In the meantime I will use Sygic 15.5.7 as an alternative .
