Very nice feature ..
I just got a Garmin EchoMap Plus 43cv..i am enjoying the Chart plotting/QuickDraw mapping/upload ..and Garmin's Active Captain app..i am also trying to get my maps onto the Navionics app ..its a process and not cut and try instructions
..I have uploaded some maps to Navionics but those have yet to be "published" on the Navionics app ..the QuickDraw uploading was EZPZ via Garmin Connect and was practically instantaneously uploaded to the ActiveCaptain app. Although I don't have the Navionics app it does offer some nice features ..especially for the ice fisherman .
