I recently bought a magellan meridian gold gps through ebay. It included a user manual cd but it does not fully explain how to load map data onto the sd card and how to get the gps receiver to read the data on the card. Also I have topo US and Canada maps that I had used on a Magellan Sportrak. Can I reinstall the map programs on a different computer and enter the magellan gold serial number? How do I format the sd card or do I need to? I cannot find any reference to card utilities on the gps menu. The firmware on the gps is 5.4. I cannot find an sd card with less than 1gb. Will a Maxwell 1gb card work? Hope you can help with these problems.
