I have 2 Garmin 8212s and a garmin 7612 on my 31 open, my question is do you Lake Michigan Garmin users use the built in maps or is there a great garmin map SD card that is better? I had an old garmin SD for lake Mi from my old 7212 but when installed it seems to be less detailed than the built in Nav map and or the built in fishing map. when I put the Lake Mi SD in the docks in my marina disappear on the chart when I take the car out the come back.
thanks
