Hi all. I am new to the forum and was hoping that someone can assist me, or point me in the right direction.
I have a oldish Lowrance Fishfinder/GPS unit. I would like to load maps onto it (Navionics or somethin similar). I know the Navionics gold is compatible and I have confirmed this with Lowrance but you cannot get it in a 1GB sd card. I know how Navionics copy protection works, but I cannot find an image of a card ( and the CID) anywhere. I also cannot find a second hand card to buy
I have also looked at OpenSeaMap from where you can download AT5 files. I cannot get Gpsbabel to convert this though. Seeing that AT5 is a Lowrance format, maybe I should just try using it directly on the device.
I would like to get a solution. I am willing to spend some money if I can make it work. At this stage I am not willing though to spend R20/30K on a new unit, maybe in a few years time I will. Need to get my kids through University first :)
Any help is greatly appreciated. By the way, I am an engineer so I can get technical if needed.
