Jim59 has it nailed.
I upgraded from a 210 which was a great radio. The new one is equally great, it's just that no-one on the design/manufacture team appeared to fully understand the nature of 8.33 implementation.
It does appear they'll need the box back in Kent to do the change but who will pay for this has yet to be made clear.
I don't know how many radios have been sold into the UK, though for the moment buyers beware!
