From what I see, it SHOULD work with 7.903 according to the chart. BUT I note that the meta that is shown with this map on the maps list in post #1 is NOT for 875_3675, it is for 875_3613 - this may be why it doesn't work. You should check this with Popeye.
As for swapping maps around on diff cards - as long as you are sure that you have a patched 7.903 navcore with a compatible (and patched) map on each installation, they should work. Just be sure that each card is fully patched/activated.
The 715 is a real oddball that does not behave in the same way as other GO's where internal (RAM) memory allocation is concerned and hence results cannot be as easily predicted. If you find a working combination - stick with it. If you experiment - be ready to get some surprises and a lot of disappointments. Most 715's seem to end up as bricks.
