Thanks for the replies, after more research, it looks like that Nifty City is not very good choice for the Gladiator. It looks like the best pick may be the Stinger Heigh10.
Has anyone tried the Nifty City 13.6 inch tesla style screen for the Gladiator? If not what is a good upgrade from the Uconnect 8.4?
