Hello,

Thank you for the tips and trics for using patched mapsource, mapinstall and basecsamp. It works fine for me and I have a system on my PC with Europe NT 2012, Topo Benelux and Topo France v2. I installed it also on my Oregon 450 using the unlocker you tipped. That also works fine.
There was just a minor problem. When I replaced tehe mapsource.exe with the patched one I got a language message and the mapsource crashed. I solved the problem with another patched mapsource.exe.

Thanks,
Parbleu
