Thanks...

...my problem is, that I've upgraded faulty nuvi 3490 for new 3590 and I've no xml file in my C:\Garmin directory since I use programs, what I've installed for my old nuvi (I've only replaced UnlockCodes.ucx so far.)

So I wonder, which program installation will generate this xml file?
MapSource, USBdriver, CommunicatorPlugin?

I don't want to try manually since MapSource is patched already, so...
