I have exactly the same system as you, also with Igo8 3.3 running. I went through the same problems with TomTom, and I have tried Route 66. I was a bit disappointed to begin with, but Igo8, which i had never heard of before, is really good. I echo all of your comments, especially that it would be better if you could have the radio on while you look at the map screen. Please let us know if you have any luck with the firmware request. My only complaint is that I paid more than you! i got mine from Ebay. I got the radio removal instructions from Hyundai USA. It was a lot easier to fit than I expected.
