I "upgraded" my car this afternoon:
Please don't pirate any maps... Universal FGII version search & replace in a hexeditor:
2500000a003090e5030054e10000a0330100a023
2500000a003090e5030054e10000a0330100a0E3 (23->E3)
0000a0830100a093ddffffea0000a0e3
0000a0830100a0E3ddffffea0100a0e3 (93->E3, 00->01)
000001e0000050e30200001a0000a0e3
000001e0000050e30200001a0100a0e3 (00->01)
50004BE2DC101BE5
DC101BE50100A0E1 (complete replacement)
(The last one was documented 2 pages ago and I'm not inclined to spell things out more clearly in this post.)
