They used a ship and a navigator to help them find their destination and the navigators were a magnetic compass and astrolabe (the stars). He could of use the blah blah!

Yes and by the 1800's they were pretty good maps.
Sighting the Sun at midday (when it is highest in the sky) is one of the best methods to determine latitude (of course you must know what day of the year it is too but that was relatively easy to keep track of). You have to be very careful if you are in the middle of an ocean and on a ship bobbing on the waves to do this properly!
Astrolabes were first widely used in the Middle Ages and by about 1450AD they were in use by navigators. They allowed navigators to calculate the position of the Sun and stars from the horizon. Their use was the first step toward scientific navigation. The great age of exploration was coincidental with their use.
They wouldn't have had to depend on the stars for navigation. If the sky were cloudy, they wouldn't have been able to use a sextant. GPS and accurate maps would help them avoid obstacles.
The answer is the Mercator projection
Navigators use the magnetic compass as it points towards the Earth's magnetic North Pole, providing a reliable reference direction for navigation even when other systems may fail or be unavailable. This allows them to determine their heading and maintain a consistent course.
