Thanks to everyones help and inputs, I was able to get my Lowrance units installed, got the new v5.0 update done to both of them this morning as well as networked and a Navionics Hotmap card with mapsharing going on both units. Now my next question, I have a blank SD card installed on one of the units to record sonar logs such as structure scan (side scan, down imaging, and sonar logs). I am having a difficult time figuring out how to do this so I can go back and be able to review all channels from recording and pin point structure or something I may have missed while on the water. Is this something that can be done from my Macbook pro? Or can I only view logs by using the units themselves? I am running two HDS 7 touch gen 2's. Any input is appreciated! Thank you!
