As the title says, is it correct to say that you cannot convert an NT Garmin map over to a Non NT map? I read up on the converter tool of which it stated that it doesn't change the file to something else. Once an NT file, always an NT file.

I have an older system that uses non NT maps and I believe they discontinued those maps in 2009 but I would like a 2011 map for it. That would be nice!!
