Yes. I have one. It's been years since I did but I recall
looking at the US manual and following the directions by pushing and holding a button that the US model uses for US/Canada/International that was labeled something different in the EU manual.
Then you again have to push the wrongly labeled button, once in US mode, to switch between marine VHF
channels and US VHF
If this vague hand waving doesn't help give me a shout and I'll dig through my paper manuals
- I'm sure I took notes ...
