Another word of caution regarding French maps. I bought a few maps last year prior to a trip to Provence. I thought I'd buy them directly from IGN to ensure the latest editions http://www.ign.fr/ The maps arrived promptly so no problems at all with that.
I'm not sure how often IGN update their maps, the ones that they sent me ranged from 1999-2005 consequently I found a bunch of stones situated within the middle of a well- established suburban housing estate which were shown as being in farmers fields on the map. I guess France is a big country and re-mapping it must take a bit of time.
Also the roads had all been re-numbered since my 1999 edition map so there was a fair bit of guesswork done.
All part of the fun of being abroad
