this seems to work on some, others not.
Mine took best part of two days...
That's weird seeing as they are all built the same way
i have the code....its just the process of waiting an hour, which i have done. then you hit PTY apparantly till CODE or SAFE start flashing....the problem i have is the PTY button dont make the flashing symbol
I just pressed PTY and the code is stored, no holding it for beeps or anything, then the radio came on.
