On the compatibility it states that you need to have mfsw to use the bluetooth side of things?

Has anyone attempted to fit one without the mfsw? I'm wondering if the module functions ok, just I would have to make/answer calls via the buttons on the phone.

I'm after bluetooth calls and streaming, but ideally would like song display too.

I've got a 2005 A4 cabrio with the concert 2, and I have the display in the middle of the cluster.

The only solutions I can come accross is:

Gateway Lite - But doesn't show song names

Gateway Pro - States it doesn't work without mfsw

Parrot - Not a fan of having separate bits added to the dash.

Are there any other options available?
