Spoke to the service manager and he basically said that if they supply and install the product, then it would be in their best interests to look after the customer in terms of warranty claims. Ford, itself, would not have a bar of it. What was surprising was that he mentioned that there was a cheaper alternative, which I assume is the CAPA unit, and that should anyting go wrong as a direct result from the Edit that Ford would have to prove it was the Edit's fault, which would also be difficult considering they cannot detect it... So there you go, an honest opinion from a dealership...so edit away...
