HELP NBT BUSINESS NAV Retrofit gone wrong

Post by osullivanjake » Tue Aug 08, 2017 12:53 am

i recently fitted an NBT business navigation system. when i first plugged the unit in it all worked apart from the navigation which i bought an emulator for, but when plugging in the emulator the screen remained black but the head unit was making noises. therefore i put it down to a faulty emulator. however since plugging the nbt back into the car without the emulator all the navigation and contacts and connected drive options have disappeared??

when i plug my old CIC entry head unit in it works like normal. Can anyone help as to why the options have disappeared and how i can get them back? or whats gone wrong, very confused. Ive attached images of the nbt when first plugged in, the wire set up of the nbt and the nbt now
