Does anybody know if the faceplates for the Audi Concert II CD head units are interchangeable to get the unit to fit flush in different Audi models, ie. A3 vs A4 vs TT, etc.? This assumes the rest of the unit has standardised dimensions across the various Audi models.

I have a faulty Concert II unit in my 2001 A3 and am contemplating buying off ebay a unit from an A4 whose faceplate has a different shape. Hoping I can use the faceplate off my A3 unit to get it to fit flush in the dash of my A3.

Any experts on this out there.

Thanks in advance
