Garmin and IGO are both Global Positioning Systems (GPS). A GPS displays a map of the current location and then calculates information, including trip distance, altitude, longitude and latitude. A GPS works in all weather conditions, day or night, 24 hours a day, seven days a week around the world. You have to convert your Garmin map to IGO format to use it on a Garmin device.
Download GPS Converter (see Resources). This is a free trial version. You only have 10 days to use this trial, but you can buy the full version of the software with PayPal or your credit card.
