Isn't ADS-B the only way to display collision avoidance data on a Garmin GNSx30 device, if you have something like the Garmin GTX330 transponder? I am sure thats how they use that functionality in the US.
When our old transponder died, and we installed a GTX330, I was really hoping we could see traffic data presented on the GNS430. We were told by the avionics engineer that we couldnt have the ADS-B enabled. Quite how he didnt enable it, I dont know, just that we dont have the traffic page available on the GNS430.

To get traffic data, it has to be uploaded from ATC, and nobody in Europe has bought the extra software/equipment to do that. They all could (as they have in the USA) but they have decided to not spend the money.
So NO traffic data via Mode S in Europe, now, or ever.
As regards emitting ADS-B data, I don't know what exactly is involved but an obvious pre-requisite would be a GPS-transponder connection carrying the NMEA data. That is trivial, but "illegal".
I don't know what extra config there is in a GTX330. I have the Installation Manual and you can find it on the internet easily enough.

On a 330? Most 330’s are the standard model which needs an upgrade to the ES version at around £1000. Then you connect an RS232 cable running at 4800 or 9600 in most cases to get the data in. Almost all non-Garmin mode s units have ES as standard. On the Trig TT31 it takes seconds to set up and it displays the status of the I/F and the position data being received.

Interesting.... incidentally when one well known avionics shop was contracted to connect the KLN94 to the GTX330, and could not get it working, despite 2 visits, and both Garmin and Honeywell washing their hands of it despite the connection appearing explicitly in the GTX330 IM, I was looking into it and one could see some of the data from the KLN94 but not e.g. the GS, so there are possibly various inter-vendor compatibility issues, and these will never be fixed because nobody wants to fix old stuff when they can sell you new £10,000 boxes 
I bet that if ADS-B became mandatory a lot more of that would surface - unless you have an all-Garmin stack.
