I've updated to the new maps - where are my old ones?

Hello All,

I recently updated to the new Ovi maps v 3.xwhatever..  it works fine, but the three or four maps I had stored for offline use are no longer obtainable.  Do I have to re-install them?  Does this mean all my favourites have gone too?  Yes, I have tried setting the new maps to look in both the SD card and the mass memory - no maps found.

Also, in what directory are the maps stored?  I would like to delete them in case new maps doesn't overwrite them (so I don't use up all the mass memory).

Thanks

All the best

Jim
