ya its not the arrow. its when im in map page or i go to the electronic compass, that its pointing wrong or it tends to move all over the place

would the best way to do this, is to get multiple 1gb cards and have Nav on 1 and topo on 1 and blue chart on 1.......ect

what does it mean while shopping for maps, some say 100k and others 24k? is one better than the other? also my compass isnt recalibrating?has anyone else had this problem?
