Multi Currencies based on iP visitor

Hi,

I’m looking for the best way to display the currency based on iP visitor. I’m using Cartthrob. My main currency is EUR and I need two additional currencies: USD and GBP.

At first, I’ve installed Cartthrob Multi Location Settings Manager and IP to Nation. In Multi location plug in i can define the additional currencies based on visitor ip. That’s OK.

My configuration is:

Fields: - Country: Global ; Channel: Products ; Price field: Price ; Shipping Field: Shipping

Currencies: - Country: USA ; Currency Code: USD ; - Country: UK ; Currency Code: UK - Country: Global ; Currency Code: EUR;

As I have only one price field for all products, using the above method there is no currency exhange, the visitor see prices in their currency with no exchange rate.

100 EUR = 100 USD

I can create a new text field in all products and store by hand the prices for other currencies. Like price_usd and price_gbp. Then in Multi currency Add on i can set new zones for fields configuration like:

Fields: - Country: USA ; Channel Products; Price field: price_usd; Shipping Field: shipping …. etc

Problem: I have more than 1000 products and I’m looking an automatic way to do it.

If i install the google currency add on the currency change on the fly so how can I set the price field in Multi Location Add on?

Any directions please? Or any other way to have multicurrencies?

Thank you very much.
