Addition of a "reset" button.

At present, when there's a problem with the guidance system, you have to quit the trip and then restart it.

While we're waiting to correct all cases, it would be much easier to have a button that restarts all systems:

• Recalculates the next instruction

• Restarts the VPS

• Relaunches sounds and voice instructions.

One way of assessing how well the app is performing would be to try and minimize the number of times users press this button.
