Gpx 1.0 or 1.1

[Mark McDonald]

What's the basic differences between saving a gpx file as 1.0 and 1.1?
Many thanks, Mark

The difference between GPX1.0 and GPX 1.1
GPX is the extension of a file for your navigation system. You can compare this abbreviation with the .docs extension of a Word file. The extension of a file can therefore tell you what type of file it is.

GPX 1.1 can be seen as an 'updated' and 'improved' version of GPX1.0. A GPX 1.1 file can contain more information and therefore transfer to your navigation system. All new navigation systems can read a GPX 1.1 file. Older navigation systems cannot understand this 'more complicated' file type and therefore you still export a GPX1.0 file to older systems.

For an old BMW Street Nav (Zumo 390) am I better to save as gpx 1.0 as opposed to 1.1 ?

@Mark-McDonald if your nav can read the extended version 1.1 without any issues and you do not have any issues or miss any data I'd go with 1.1.

@Mark-McDonald the Zumo 390 will work well with GPX 1.1 that's what I use with mine.

@Mzokk Thanks

The GPX 1.1 schema was released on August 9, 2004. GPX has been the de-facto XML standard for lightweight interchange of GPS data since the initial GPX 1.0 release in 2002. GPX is being used by hundreds of software programs and Web services for GPS data exchange, mapping, and geocaching.

Just 2 years after the introduction of GPX 1.0 version 1.1 was already released. There has never been a new version ever since. It is safe to assume version 1.0 is obsolete if you use navigation software and hardware not older than 2005.
