I’ve just managed to get a response from DTUK - apparently my box is not compatible after all, as the new modules do not have a 12v supply and ground like my current one. The new ones are powered by the sensors? Not entirely sure how this works but that’s what I’ve been told by their support guy - however app control isn’t required and is still an optional extra...
Bit frustrating that I will need to replace the module as the new boxes have been out 6 months and I asked the question in October and was told it would be fine
I suppose getting two cars for the price of one was a little too good to be true haha
