Topic: 987C SI Compatibilty with Navionics SonarCharts Upgrade

[Consigliere]

I'm running a gold Navionics chip in y 987C SI and have been looking at the SonarCharts upgrade from Navionics.  I would like to do my own charting because local waters on the chip are not very detailed.  Is the 987C SI compatible with this upgrade?  Will it show 2ft contours that the SonarCharts is apparently able to deliver to a Gold chart?
