The link I posted was to the A6FR (for French), not the A6E. As stated previously, they are different, in that the FR model has an FM filter, which cannot be purchased separately.
ICOM FRANCE : Produits Radiocommunication : Accessoires Platines et filtres : FL-IFFM2
There is no need to try to pass one off as the other, because the UK aircraftradio licence will be accepted in France.
