Upgrading to Trophy Connect Retrospectively

[easynet]

Is it posable to upgrade a MG zs trophy to a connect model is it just a plug unit or is it built in

I read somewhere that it cannot be done as an after market it has to be done during the factory build

I've modified the thread title in order to differentiate it from generic threads asking what the differences are between a "Trophy" and "Trophy Connect" version.
