Pretty typical for tech that is that old. SF2 doesn't make any sense to use and I don't know of many people that do use it today. 


It'll still work on SF1 or RTK past that date. Just not going to get factory support if there's an issue. Not that they've had any updates for a 3000 in years anyway 


3000's with radios for RTK will be a very cheap and reliable way to have signal yet (my opinion)
