I am having a problem transferring routes from my SD card to my GPS. I currently have 15 tracks and 15 routes on my SD card however when I try a data transfer be it merge from card or replace from card, my 15 tracks will transfer but only 6 routes out of the 15 will transfer. I take the SD card out and put it in my computer and all 15 routes are on the card. Any suggestions to what I might be doing wrong?
