I used a tutorial by dcrainmaker on how to download free maps and I used one called openseamaps for east Australia and installed it on my garmin fenix 6 pro.But I cannot see any depth contours(which is what I am mainly looking for).My other option would be buying the garmin bluechart g3 for eastern australia.If I buy it and install it on my fenix 6 pro, will the map show depth contours ?
