Garmin Echomap 75SV Memory Card
My Echomap doesn't appear to read my Sandisk Micro SD card.
I created a route in Memory Map which I saved on to the card in GPX format but when I put the card in the plotter, it doesn't seem to recognise it - there certainly isn't an option to transfer the data.
The situation is slightly complicated by the plotter not having a power source independent of the boat.
Can anyone successfully transfer routes from a memory card to the 75SV and if so, what type of card do they use? It could be the card at fault or it isn't compatible with the Garmin.
Has anyone jury rigged a power supply so they can flash up their 75SV at home?
