If I understand the model correctly try this one.

this is the user documentation for the device.
Page 10 shows the elements. There is a frame that installs to the back of the dash and the device fits into this.

I am looking at the Bluetooth Amps and using my phone as the total ICE stack at the moment. I am just going to leave the 2011 Alpine thing to fill the hole in the dash.
On the Coupe there is apparently a 4 channel amp under the passengers seat, so I would swap this out and link the iPhone up to in on BT.

Everyone loves a Morgan. Even me, unless it's broken again.
