You need to have collected 80 Gold Bricks before you can input these coordinates.
You can find the legendary coordinate QR slabs if you wish but they are not actually needed. I will post a link near bottom if anyone would like to scan QR codes. SPOILERS BELOW
Go to your ship to enter coordinates into white bar on right side, make sure you're on the x galactic zone
Type the following x y z digits in to find the map, then you'll have to use them again to find each legendary brick.
You Will have to delete worlds as you progress as the galaxy gets full very quickly.
Here's how i did it:
Looking on mini map you'll see a white arrow pointing north.
x=East/West Travel west/left for a -negative number or East/right for a positive one.
y=elevation/ up for a positive number /Down for a negative number
z=North/South Travel North for a positive number or south for a -negative one.
