I have the Marine US app for my iPhone. How do I delete tracks from the screen?

Actually, the track is just visible in LIVE when the application is ON.

So with the multitasking feature inside (iOS > 4), you need to force to really quit the application.

For that, use the Multitasking bar to close any app you want.

Here‘s how:

• Double tap the Home button to bring up the Multitasking bar
• Press and hold anywhere on the multitasking bar until the icons on it start to wiggle.
• While they are wiggling, each icon has a Minus sign symbol above it.
• Press the Minus symbol above Marine US application to close it down.

then restart Marine US as normal and it will start a new track
