Nav disc ver6.6 for 2005 fx35

[osumason]

We recently purchased an 05 fx35 for my wife and it has nav disc 6.3 and I would like a more updated one, but don't want to spend the $190 on a 6.7. I found a ver6.6 and was wondering how updated that is compared to the 6.3?

There wont be much difference from 6.6 to 6.7The only things that get updated are the POI and any new streets. I dont think there are that many new streets in a years time.6.6 should be ok
