VXOC Astra-J/GTC

I'm having an issue with my new aftermarket radio that i have fitted, everything is working correctly except for the main screen at the top as you can see in the photos, all the other installs ive seen show this screen working, 

also in the connects2 book it says that i can access the old settings menu with my steering wheel controls, so this screeen from what i can tell should be working

any ideas what the problem could be?

this is the kit i have installed

Have you cut the black wire on the speaker plug?

If you look at this how-to it show's you which wire I'm talking about
