Can anyone speak to whether Model HC250 is still supported and/or is there an "end of life" for this unit? I had a dealer tell me it's a very old unit which is no longer supported, but then said something like it reached it's end of life in August 2023 and would no longer work. My HC250 suddenly stopped working early January 2024. I'm wondering if I should try replacing with a new or used/certified same model as a replacement with a new model is quite expensive. Also, I have not tried resetting the unit to see if it will work; however I will lose all programming. Thanks
