Nope, although I've only done it once... I had to kind of bend over to make sure i was yanking on the right thing, but that's not too bad.

I picked up one of these to test with: [ame=http://www.amazon.com/gp/product/B00LLER2CS?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00]Amazon.com: SanDisk Ultra Fit™ CZ43 32GB USB 3.0 Low-Profile Flash Drive Up To 130MB/s Read- SDCZ43-032G-G46: Computers & Accessories[/ame] I filled it all the way up with my mp3 collection and have been pleasantly surprised at how well it works! My directory structure is each album gets its own directory, sorted into genre folders. So it goes about 2 layers deep in most cases, with up to 30 songs in each. The first index took about 2 minutes, but now it takes about 30 seconds until all the music is loaded and I can get to anything. The fact that it resumes from the last point is a HUGE plus. Listening to something as it indexes is nice. Shuffle works well for me too. I haven't yet turned it off near the end of a song. I guess if it's that big of a deal you could just pause it for a few seconds until indexing is finished? I don't know, since I'm on shuffle most of the time I don't mind the 1st song of the 1st directory playing, after all it will just continue shuffling after that. Or maybe I'm missing something? I'll go test it.

Does the directory structure and files need to be indexed every time you start up the HU? If so, how long does that take? I had a similar set up with a previous car and it took forever every boot....
