Currency / geolocation

I have the following problem:
Default currency: EUR
Second currency: US$

Only for USA and Canada, I want to display the US$ currency, all other countries shall have the EUR.

I have a high number of zones (all countries; imported list) who do not yet have assigned a currency (it's impossible to do it by hand, too many...) - except for USA and Canada with US$.
Is that enough to work? Does the default currency EUR apply for those without the currency specified?

The geolocation plugin is active.

Thank you!!

Hi,

Yes with this configuration it should work as needed.
