If you launch the LG PC Suite II it should then prompt you to get connected and find your phone after a few seconds. Once thats done, you should get the landing page that gives you the options, Sync, Games, Music Etc,
When I clicked on music, it launched the app, then threw up the not connected message. Reason being the phone is in the wrong mode.. Most phones will prompt you which mode you want to connect in, but the cookie doesn't by default.
You'll need to disconnect the USB cable from the phone and then go to
Settings > Connectivity > USB Connection > Music Sync (or always ask, in case you sometimes will want to sync or use storage)
It will confirm its been saved, and then you can plug the cable back in.
Your PC will probably say that there is new hardware detected, just leave it for a minute or two to finish doing its thing and then you should be good to go. Your phone should display "Music Sync Connected" with a cancel button at the bottom of the screen.
If you launch the music app again now from the PC Suite, your phone should be connected and you'll be able to transfer your music over.
Another way of doing it is to connect in mass storage, and your PC should then just see it as an extra storage drive and you can just drag and drop your mp3's into the relevant folder - having said that, mine didn't have a music folder when I tried this way, but that might be because I've not got any music on the phone yet!
Personally I'd stick with using the PC suite, at least that way you know that the phone will know its got music on it!
