I have a Zumo 660LM on my 2011 RTS. The LM indicates lifetime maps, and they have been updated several times over the years. I use Garmin Express, but have not seen any map updates for what seems to be a very long time. They used to update the maps about three times a year. I understand the 660 is a discontinued model and "lifetime" is not my lifetime, but the OEM's determination as to the useful "life" of a product.

Today I went to GARMIN.COM, and did a "chat" with someone and asked if the map updates were no longer supported. He said that the maps were still supported for the 660, and that Garmin Express would notify me if a newer map was available. He did not seem very knowledgeable and had no idea what map version should be on the device, or the next time new maps would be available.

The current map on my 660 shows as: Full Coverage of North America 2019.20. I do not know if that is the most recent, and could not find anything on Garmin's site about the map versions.

Anyone here have more info??

Thanks in advance

Bill
