Garmin Express wont recognise Itunes

I just learned that Apple streaming services block any use on Garmin (or other unsubscribed) devices. 

I have the exact same problem. I moved around de .xml file and changed its name, but it still doesn't work. I don't understand why Garmin Express doesn't allow to browse the computer

I've been having the same problem. It's so frustrating that Garmin know about these slack design issues but don't even update the help pages or respond to forum/support questions and rely on the "community" to ad-hoc resolve every trick technical thing like this. Very poor support and it really should be a simple fix for anyone who knows what they're doing.

Anyway, back to the file linking - yes, this seems to work well but you need to remove the "/H' tag. You don't need a Hard Link, just a Symbolic (soft) works for this purpose and doesn't require consistency in the disk format type.

So, change, 

mklink /H "C:\Users\username\Music\iTunes\iTunes Media Library.xml" "D:\Your_Custom_iTunes_Folder\iTunes Library.xm"

to

mklink "C:\Users\username\Music\iTunes\iTunes Media Library.xml" "D:\Your_Custom_iTunes_Folder\iTunes Music Library.xml"

Obviously you'll need to substitute in the file path and filename of the Medie/Music library - it seems that different versions of iTunes have different names for this xml file (Media Library, Music Library or just Library), so check in the default c:\ drive iTunes folder.

This so far is working for me and although it's a pain plugging in to get updates, it took only 20 seconds to transfer two podcasts which previously took the best part of a hour to suck up over wi-fi with one of the other Music "apps".
