Garmin nav data update

Does anyone know if it is possible to load a 400 WAAS IFR card from a GTN 650 IFR update cycle? A friend has offered to give me an update cycle that he won't need. Thanks

Don't think so. In fact, I don't believe his GTN 650 update can even be used in a different GTN 650.

Do a search, there is a guy here who offers that for a 430. Not sure he would have the coverage area you need though.
