I bought a Honda HR-V, which came with a media center (CM) with the Garmin GPS program. (I do not know the brand of the CM). I know it's the same CM Civic ELX 2016.
I tried to include the warning radars and spines by intuitive methods: use a USB stick with the GARMIN folder; connect a notebook with garmin express in USB CM to try to locate the internal memory of this.
Having no positive result, I turn to friends, hoping to find a solution of how to create the "POI" folder in that Central.
