How to automatically set currency?

Hi!
I use Hikashop 1.5.7 business edition.
Geolocation plugin is enabled.

my real location - Russia.

I've set 3 country zones: Usa, Canada, Russia.
Currency for Usa, Russia is set to 'usd'.
Currency for Canada is set to 'cad'.

default system currency is 'cad'

when I place new order - only 'cad' is selected.

ipinfodb.com determines my country correct (Russia)
Api key to plugin is set correct.

How I can set currency to 'US' to Russia, US zones?

The currency is only set once when you open the first page of your website on your browser. Then, that is not triggered again.

So that's probably why you think it's not working.
