Just to summarize what I have learned.
Make a route in MRA with Here map using shape points.
Making sure to have the first point when leaving a bit further down the road to make sure that the route starts.
Widen the and colour the track with the garmin settings.
Save as 1.2
Question: When using shaping points and I place one next to a petrol station and name it Petrol and add a symbol of a petrol station, will it appear and can I select it when navigating or do I have to make a via point?
There is no specific need for using HERE as the base map when creating a GPX. It doesn't matter at all for 1.2, and if you have enough shaping points, it shouldn't make a difference using 1.1.
HERE can be troublesome unless you actually need it for the NN app, where it's required. I've been using OSM exclusively for some time now, and it's a solid choice.
