The unit itself is already update with the latest firmware and software however the unit does not seem to be playing the frequencies. I don’t believe the frequencies on radio reference/HPDB are up to date. I have looked at radio reference and it appears they are creating a new system which is a TDMA system and I know uniden does not cover this system. I am just wondering if this is what they are using already or plan to switch to this system. If they are not using this TDMA system then I should be receiving this area but it just will not receive.
