To transfer the sea chart in the temple to your map, open the map up so your map is on the bottom screen and the map you want to copy is on the top. Close your DS. Now open it again. You just transferred the sea chart.
find the sea chart that matches the other sea chart upside down and close the ds. and it will be transferred on your map.
If you meant on Phantom Hourglass, you close your DS. I knew how to do that when I was 7.
Simple close your d.s. For like three seconds and there you go
all you do is close your ds and open it again

You can't find the Old Sea Chart in FireRed.
you will find a picture of the sun, if you tap the sun it will say"press the sacred crest to the correct sea chart to transfer it. The temple will only open to the wielder of the sun key." That means you have to tap "sea chart" in the lower right of the screen. Then you close your ds and open it again. Then you leave and go to the spot in the sea on your sea chart where the green thing is and use the salvage arm. If you get the chest you get the sun key.
Close your DS Then open it again DON'T TURN IT OFF
After making sure you're as far as you can possibly go and need the second sea chart, go to the temple of the Ocean King to get the second sea chart.
