Unfortunately, it is not possible to use the Cambridge Audio Connect App with the CXUHD.
The Connect app is only designed to work with our range of products which incorporate our StreamMagic streaming platform. These items include the CXN/851N and the CXR120/200 as well as many of our other streamers.
Our range of universal Blu-Ray players do not incorporate this module. However, you are able to stream from a UPnP server via the on-screen menu.
