Third Party Maps on MapSource

[davidr]

There are quite a lot of Third Party Maps available for MapSource, etc. But most/all of these are not routable so don't be surprised if you try downloading route that these won't be shown correctly

yiep, most of them are not routable and believe me it a pain in the a$$ to make em routable
i have tried a lot to convert an existed map to a routable one but always i stuck somewhere
