great, thanks bud. can't wait to tinker with it. mine came with the 4.0 software so i'm all set there.
do you run yours in split screen, sonar/chart? or do you leave it in sonar most of the time?
if i'm in an area i'm very familiar with, i leave it in full screen sonar. otherwise, split screen sonary/chart.
another great feature is the overlaying of data. all customizable. on my sonar screen i have the depth, gps speed, water temp, time, and battery voltage. you can move them wherever you want and size them to your liking.
