Ok - I just picked up my 2012 Volt yesterday and immediately loaded it up with 8 GB of what was well organized music on a USB stick. I'm obviously missing something major.
I can browse by folder - sort of. It flattened my directory structure. I had things organized by Genre/Year/Artist Letter/Album. I now apparently only have folders for Album. Disappointing to say the least. I then go looking for "More songs like this" - only to find the option unavailable.
From HDD: There's no folder browsing *at all*. 30GB of music storage without folders?!? I then go to "More like this one" - out of 1,600 songs, there should at least be one more, right? No. No matter what I select, I only get the song that's playing. To make it worse, once I do that, that one song goes into infinite loop mode - even when on shuffle. And finally - I have a son that likes an artist starting with the letter L. I've found that with just 8 GB of music, it's a nightmare trying to get to the L's! The best I can do is hold down the page down button for a minute (or two) as it scrolls through things - but that just sucks. I know I can add the artist as a favorite, but that's not really the point either. Why can't it accelerate as it scrolls, or allow me to move the scrollbar to the rough area I want it to be?
Before I got this car, I was thinking how much I'd love to be able to put in a bigger hard drive. Now that I know how it works, I'm thinking that anything more than 4 GB or so is a nightmare to work with!
*Please* tell me I'm just missing some obvious button or option somewhere...
