I have a question regarding about when you delete a way point. I have a Garmin handheld GPS. If I delete a way point does that open up that way point for adding another way point to that slot. For example: On my GPS, I have way points number 001-100. If I delete way point 57. When I add the next way point, does it become the new way point 57 or does it go to 101? Thanks for any responses.
