I posted the following in the Quickdraw sticky but haven't had a response so I'm posting here. Getting ready to update my Lakevu chart and would like to keep my Quickdraw contours.

I have the Echomap 93sv Plus unit and every time I've updated my charts with an SD card, I lose my Quickdraw contours. Based on the above, if I save the old contours on my pc and download the new chart from Garmin to a blank SD card and then insert that card into pc and add the Quickdraw contours to the new card it'll work?
