Ok, I've had the radio for just about a week now. It took me until Thursday night before I was able to get the D-Star setup and working. You have to register the radio and your call sign with the local repeater(took about 24 hours), then figure out how to program the Callsigns into the radio(Much easier if you follow instructions off the internet and not Icom), then program the D-star repeater freq. into the radio. At this point you can use the Voice side of D-Star. Now there is still more steps required to connect you PC up and use the data side. Once you have registered you will have to log back into the system and update your information. Primarly adding your callsign next to an IP address. This is as far as I got since the battery died on me well I was being walked throw the setup with the repeater sponcer. I will update you further once I have recharged everything and have a chance to play again.
