Is there a listing of Garmin GPS devices that have a WNRO problem - their support page doesn't state which ones have a problem. We have used their 17HVS and 16xHVS units. Their website just says; "Our testing shows the vast majority of Garmin GPS devices will handle the WNRO without issues." https://support.garmin.com/ms-MY/?faq=zWQY6Z2kFiAuY9kDnDBgZ6
