Hi folks
I have recently been doing some research on GPS replacements for an organisation and noticed that very few Garmin GPS's support the new GDA2020 datum. In the usual Garmin fashion they don't actually spell out which exact models have access. Don't let the 'new models' and '2019' in the document below fool you into believing something like a new Etrex22x will support it.

Some contact with a local supplier indicates that maybe only the 65 and Montana series currently have the ability to use GDA2020. I am still awaiting a reply from Garmin of which exact models, so be cautious if you are replacing a GPS to get these features.
Maybe folks with newer GPS's could indicate if they can select GDA2020 as the datum.
