Hello . Firstly I apologise if this has been covered before .

I have a 2013 Octavia with a Columbus high media unit with the 8 inch screen .

I want to upgrade to the MIB2 system with android auto , I have been advised that I won't need to change the screen as it will be compatible,  but have been told I'd need to upgrade the USB .

Does anyone know if this is correct?? 

Thanks in advance 

Adi

Sorry , I ment to add , I also want to add a subwoofer ( not canton ) , I heard that the columbus unit can run a sub , would this need coding ?? 

Thanks
