i currently have an iPod classic 160gb connected via usb to my car stereo, where I have synced my entire iTunes music library, taking up almost 80gb of space. I control it through the car's factory stereo system (BMW iDrive). I am happy with this setup, but recognize this iPod won't last forever. My biggest gripe is having to sync new music and playlists to it when they are added to my library (by physically removing it from the car, connecting to my computer, etc.) I am considering a 128gb iPod touch to replace the classic. I really enjoy the ease of iTunes Match with iPhone and iPad, but I want to know about some possible limitations of using it in my car and keeping it always upated with the most recent downloads and playlists. My car stays in the garage at night, and my home wifi can connect to devices in the car, so automatically downloading new music to the iPod touch could happen then. If I get all of my music initially onto the iPod touch when I set it up (just load all artists, albums, and songs) and turn on iTunes Match, I will see all playlists when it finishes matching.... No problem there. But when I am driving and away from wifi, will the playlists disappear? I don't want to manually add all the playlists, since that is time consuming, and I want to have the playlists automatically update like they do with my iPhone, and via wifi in the garage will satisfy that. And there is no consistent way that I can find to connect the iPod touch to my iPhone's hotspot automatically, every time I get In the car. I really just want a low-effort way of maintaining content on an iPod touch while leaving it always in the center console. So, my question is, without wifi or hotspot, will I be able to access things like playlists or even matched songs (but not downloaded) and play them? Or do these iTunes Match features disappear in absence of data connection? Thanks for your help.
