Thanks, can't post a "snapshot" yet as I do not have a blank SD card or SD reader for my PC.....Yet! I'm actually getting a good contour map with the Navionics platinum lake map chip installed. But only when reading the Navionics chip, not from whatever is installed in the unit. What I cant get is the 3D or satillite imaging when the unit is reading the card...just the contour map. I'm sure it's there, I just dont know how to access them. Neil
