Merging Maps


I have no problems with merging maps - but would like some information on the config files.
Do the two files merge or does the original map (map being merged into) become the dominant config file.
If the two config files differ greatly does this pose a problem ??

Once you merge, it is permanent, and can not be un-merged, (as it is one route with one config file) ... It's sort of like marriage :hehe:
Thanks again - not sure about the marriage part !!
I have been married 57 years and we have only had one fight - started the day we got married and has been going ever since !!!
Got to say "got a good one" and thoroughly recommend it.
