Query: Doesn't support Explorist GPS units

This software does NOT support the Explorist series from Magellan. For that you need Magellan DirectRoute v3.0, which is part number 980654-04. Amazon doesn't currently carry that version. If you have an Explorist, do not buy this, go elsewhere and get the correct version.If you have an older Magellan GPS, this should work just fine.
