Navigation Map Updates?

[UnderDog]

I just bought this 07 a week ago. It still has the original maps. I wondered if someone upgraded to the 10-11 and might have an old to them 9-10 map DVD they would sell at a lower price.

Also, when will the 11-12 map come out? If you are about to purchase that and it comes out relatively soon, I would be interested in your 10-11 map.

I'm not looking to download a copy for free, just trying to get a newer map for less than the $149 price.

Thanks,
Sam
