The terminology can be confusing. Your unit came with a basemap. When you add more detailed maps to the unit, that is not considered by Garmin to be an “update”. You are just adding detailed maps. To do that, you have to buy an original-install version of a map product. After that, you can buy updates for that map product when they become available, usually about once a year. You can skip updates, but you can’t start with an update. You have to start with a full-install, or original-install, version. Unfortunately, the original-install versions are not labeled explicitly as such. They just don’t say “update”. I hope this makes sense.
Bottom line: You shouldn't be buying any product labeled "update" at this point.
