Can I put the composition colour from my t6 into my old mk5 golf?

I've googled and people have done it, I think, but how hard is it? It would just be nice to have blue tooth to play from devices. It seems you need an adapter and to remove the CP and possibly other things to prevent battery drain. Anyone done this? I'm starting to think it's not worth the bother when you can buy plug and play units for the older cars that have more functionality than what I'm planning. It just seems like a waste not to use it for something.
Cheers

Nobody replied to this? ... I feel l also want to know if they can be fitted to MK5 or MK6 Golf's or T5 transporter or even caddy? .. Because PQ discover media will fit in most of these!
