It should automatically show once you have he micro sd in the slot. To be honest, the overlay is pretty butt! Only is land imagery and very grainy when barely zoomed in. I went through all the settings and found a blend of both the overlay and regular chart map.
Hello everyone. I have a Garmin 547xs w/Bluechart G2 but my issue that I am having and not sure if anyone of you also is that anything under 3ft of depth will not read and only blink and that is also while I am running or poling. Does anyone else have this same issue? I contacted Garmin and the person on the phone had no clue on the performance of the machine. She told me that it reads over 5ft which on an Ankona Copperhead I need something that will show me a depth of at least 1ft. The transducer is flushed with the bottom of the skiff so it looks fine to me. Does anyone have any suggestions? Also I did not know that in order to view the downVu you need to purchase a separate transducer for that option.
