I can't vouch for much other than what I have personally seen which is limited, but obviously to decode a mdc Id the radio has to have a display. I know that the motorola pr400, cm300, ht1250, cdm1250 and 1550 all can display it, as well as the kenwood tk x180 series with the most recent firmware (both mobile and portable). With all of these you have to enable it in programming.
