I have a TT 720 and have been installing new navcores and maps for years. It is my own device, no problems there.

However, my uncle has asked me to put the New Zealand map on his TT750 Live. I don't want to clean install because he has other maps, favourites and other stuff he doesn't want messed with.

My question is therefore, can I (and if so how do I) put a New Zealand map on his device without touching much else? I'm happy to patch his navcore if that's possible as long as his TT Live services and everything else will work 100% as before. i.e. I don't want to completely replace the whole system with new voices, menu styles, hacked services etc..

Can anyone help or point me in the direction of a tutorial/guide?

Thanks
