check your fuses first, you could have simply a blown fuse.

I have recently purchased a 2005 Stilo Abarth with connect nav (not sure if nav+ how would i tell?)
Connect NAV is a big colour screen with a row of buttons under the screen.Looks like this one on Flea Bay
Connect Nav+ is the one with the colour screen. Connect Nav has a smaller black and red screen.
