i got this unit about a month ago and got to use it about 3 times ,still learning it but just curious about the gps, can i upgrade the map on it , witch setup is better and anyone have 1 laying around they want to get rid of??????
you can buy lake map cards for certain areas of the US...depending on which brand you buy differ from what lakes they have on them.... look for fishing hot spots and navionics map cards on google!!
make sure you check but i think it takes the micro sd card and most of the lake cards are the standard size sd ,i'm sure you can order it online but not sure who carries the micro ones here in town,
