2 Garmin car units, 1 Instinct, 1 1030, 1 1040, 1 Etrex. Thats "6 Garmin devices at the same time". Do I own 6 Garmin cycling devices, no. I do own 3 devices that do get map updates when suggested, but I stated the Instinct does not get a map update. I no longer update the maps on the Etrex or 15 year old car unit, not sure there are map updates for those, no longer in use, so dont care. Not unusual for the message from Garmin about the time frame for a map update to state more than an hour. Close enough to hours as far as I care, but I'm certain you will (as typical) feel the need to argue that.
