    PS22 compatible with GPSMAP 721xs

    Garmin doesn't list the compatibility of the older GPSMAP models for newer devices, such as the PS22 or the GCV20 box anymore. Does anybody know whether they are compatible and just not listed, or really incompatible. The 721xs can run the PS30 and 31 without issue.
