Sat Nav maps

Can anyone tell me where I could get downloads of Orlando maps at reasonable prices or even FREE!!!!!

We have our own sat nav, but Garmin want £90 for a download, propbably cheaper for us to buy a new one out there. Was just wondering about any sites though.

Thanks

there have been posts on this before and I think some said they could be found on e bay for florida only at a reasonable price. I am going to download when in usa as its priced at $99.99. To do this you need a resident though which I am fortunate to know one. Not sure what else you can do, sorry.
