GPX Pro 8

finish line to be, and set the start/finish line via the GPX’s menu system (Track options, Set start/

finish line of a new track). This point will now form the basis for the start/finish line when you

start racing the track. Please note that you should be no more than about 50 feet of where your

vehicle will cross the start/finish line in order for the GPX to recognize it while you are racing.

At any time, you may move the start/finish line for a track via the menu system. Please note that

when you move the start/finish line, it will apply to all sessions/laps stored in the GPX, and

therefore the lap and split times will be recalculated for each session at that track. When you see

the message “Recreating summary information – please wait”, this is due to the recalculation

necessary when moving start/finish line or splits.

Under unusual circumstances, you may need to use manual track selection as opposed to the

automatic methods. See the section Manual Track Selection.

Adding Splits, or Changing the Start/Finish Line

For an existing track, you can either move the start/finish line, add split points, or remove split

points.

In the menu system, go to Track options, then Change start-finish or maintain splits. You will now

be allowed to select from the available tracks. Pick a track using the Left and Right arrows, then

Select. Then choose whether to move the start/finish, add a split, or remove all splits. If you

move the start/finish or add a split, you will see an animated dot moving around the track. To

stop it near where you want, press either arrow to stop it. Then you may press Left or Right to

fine-tune the position. When you are happy with the position, press Select. You may press Menu

to abort the operation.

Whenever you modify the start/finish line or splits, the lap times and all summary information for

each session at that track will need to be recalculated. That calculation will occur when you view

a session at that track. You will a message stating

Recreating summary information -- please wait, and do not power

down...

This indicates that the recalculation is taking place. It generally only takes a few seconds.

Track Variation -- Clockwise vs. Counter-Clockwise

First, assume that you are letting the GPX initially determine the start/finish automatically. Also

assume the first time you race this track, you do it “clockwise”. The GPX will determine the start/

finish, and at the end of the session, you will rename the track from “NEW TRACK 1” to “MYTRACK

CW”. Now, the next time you go to the track, you start racing, but you race in the other direction.

GPX will determine that you pass by the same start/finish line, but it detects that you are going in

the opposite direction – so at the end of that session, it will prompt you for a new track like “NEW

1 2 ... 8 9 10 11 12 13 14 15 16 17 18 ... 100 101
