Auto Currency extension tracks visitor's IP address and automatically changes the store currency to the visitor's location currency. Visitor can switch to his/her desired currency at any time.

This extension uses two IP Address databases for IP Address lookup. One is MaxMind's GeoIP and the other is Webnet77's Ip2Country database. Shop admins have the option to choose between these two databases. The default one is Webnet77's Ip2Country database.

Just install the module in your multi-currency enabled Magento shop and the module will work on the fly.

No extra configuration settings is to be made.

However, you have the option to Enable or Disable the module & Choose IP address Database Source from configuration setting:

System -> Configuration -> CATALOG -> Catalog -> Auto Currency

By default, the module is enabled and the IP address database source is Ip2Country.

This extension should run immediately after installing it. If it doesn't work then please check for the following:-

1. You should first setup/enable multiple currency on your shop. Here is about How to setup multiple currency Magento shop?

2. Sometimes the extension doesn't work due to browser cache. Please clear your browser cache and try reloading your website. Or, try opening your website in another browser.

3. If Caching is enabled then Refresh Cache (System -> Cache Management)

4. If Compilation is enabled then Re-run Compilation (System -> Tools -> Compilation)
