It is unfortunate with some of the issues people had with the A3. Unfortunately the A3 has been discontinued and there will be no further support for that model.
However, saying Amiko has no support now is a false statement. Amiko is very much alive and producing new models. They have worked with me on doing firmware fixes a couple of times, before I decided to start selling Amiko again.
I am also actively working with them now on current models. Also anything that I sell I fully support and back.
There are what seems like 100's of FTA boxes and sellers on eBay that sell daily, that will never support. They sell and forget about you.
I will never do that and never have all the years I have been in business.
Let's not let one bad car dealer make you never want to own a car again, and go back to walking.
