Hi, my old CCC unit packed up so I ended up buying another newer unit with 8 programable buttons. (old unit was with 2 slots without buttons) when I plug in all worked except voice input. I went to independand garage and they told me they have to change vin on the CCC in order to activate voice input so they change it. After they had changed the vin the 8 programable buttons stop working. They try to reprogram the CCC But did not manage to get buttons work or voice input. I was told unit does not accept codes if that might be the case. Does anyone know any garage or person in London or Kent area that able to activate it so it works properly. Thank you.
