1) send it in1.Did you upgrade the board yourself or did you have to send it in?
2. Did you pay for shipping or did they?
3. How long did it take?
4. Was it free of charge to upgrade the board?
Just curious. I get the anthem allure. I still have my mrx500.
2) it was during a warranty repair so they paid for the shipping in that case. But you would have to pay for it generally.
3) it was 4-6 weeks including the warranty repair.
4) no. I paid for the upgraded board.
All software upgrades including ARCG version upgrades are free.
I just did a cursory search and Anthems website has instructions for upgrading the board yourself. So it looks like you can do it yourself now. https://manuals.anthemav.com/8k-upgrade/
