Does 945 LTE has 8GB of storage to hold music?

If i delete all the map on my watch, then can i use all 16GB storage for music?

If I plug my 945 LTE into my PC, I see a single user-accessible MTP file system with 14.3 GB of capacity (roughly 15.5 billion bytes.)

Maps and music live in the same file system, so I'd say you can use as much of it as you can for music, unless there's some kind of artificial restriction by Garmin (such as what they do for Connect IQ apps.) The only thing you can do is try. (Maybe you should backup your maps before deleting them)

I will say that maps on my device (in North America) are 9.50 GB (~10.2 billion bytes). Something else doesn't add up because a tool like Treesize shows that 9.9 GB is used on my watch (9.5 GB of maps, ~300 MB of music, and other very small files such as activities and sport profiles), yet the OS reports that 13.6 GB is used (and only 779 MB is free). I don't know how to account for the other 3.7 GB. I get the same result (9.9 GB used) if I select all the top level folders in Windows Explorer and select properties (I have Explorer configured to show *all* files, including hidden files and "protected system files".

(I'll try syncing with Garmin Express and seeing if that clears up the problem.)
