I have a 64s and was trying to enter my own coordinates. I press Mark, to mark current waypoint. Then I went to edit it to a new destination. \n\nThe new coordinates had one less digit than the marked waypoint. I could not delete the extra digit. I entered the N and then next line for West. But it would not let me go past the W (except I can switch from W to E) to adjust the W coordinates. \n\nIs this a limit of the 64s or is there another way to enter your own set of coordinates? I have no issue entering coordinates in Goggle Maps.
