Radio/Sat Nav Fault

Morning! 

Having a slight issue where the radio in my 2016 Vrs Tdi randomly restarts itself when driving. Bolero system

I notice the compass direction on the main driver display will stop and just display - - then about 10 seconds later the radio turns itself off, but then turns back on without me pressing anything. 

Had a look on the forums and possibly the ignition switch?? but can't seem to find anything solid. 

Any advice would be great 

Thanks in advance
