Been here awhile...
Before I got my iPhone, I used a 32GB USB stick formatted as FAT32 with no issues.
I haven't tried using the USB yet. You don't think picture files would get in the way while listening to music would you? For each album, I have cover art and all my files are .wav
ASHDUMP,
I'm most interested in the outcome of when you plug it in and run it for a few days. I had a 320GB hard drive (formatted to Fat32) but was MAJOR disappointed as it kept resetting every once in awhile. (When I say resetting, I mean it keeps going back to the first song)
I had 73GB and over 11,000 songs loaded.
I had also tried a different hard drive and the same thing happened.
I now use 4G USB drives and have no problems AT ALL.
Please keep us posted if it works out for you.
thanks in advance
When you say, "resetting" do you mean every time you turn the car off and then turn back on? Like it doesn't stay in the same folder or same song as it did right before you turn the car off?.
Good deal! I'm glad you got the HD to work well in your Genesis. Did you lose any disk space when reformatting? 1TB is a lot of space!!!!
Whatever you do, please make sure you have a backup of the hard drive you use in the car. Not only are most such drives not meant for vibration (that's why automotive hard drives are ridiculously expensive and low capacity), but shutdown is unpredictable. While the head unit is probably only reading the drive, you never know how fussy the drive may be.
- I noticed for sure today that the "random" feature does not randomize the entire disk's worth of audio. Based on my non-extensive, non-scientific testing, it seems as though it picks a certain number of sub-folders (at maximum) to use for the random playlist, and then also limits that playlist by track number as well. I have no idea what the software limitations of this feature are, but they made themselves obvious to me today. There are several reasons for me coming to this conclusion, but I don't have the time to write about them now.
The "random" feature is still very nice, IMO, but not as perfect as I originally thought.
- I also noticed that the DIS menu would get "hung up" or stuck sometimes while the system changed from song to song (which are in different sub-folders) when on the "random" setting. This did not happen a lot, and did not happen consistently, but when it did, it was quite annoying.
Good advice, dataguy. With that in mind, I went ahead and did some further testing today. I used my 1TB drive (re-formatted to FAT32) for all the tests.
The first thing I wanted to test was load/response time of the system when a USB device filled with a large quantity of files was connected. I copied my entire music library (I rip every CD or DVD-A I buy) on to the external hard drive -- all 9500 tracks. Altogether, it comes to 620 hours (or 3.5 weeks straight) of music. The songs are mostly encoded in .mp3 format (with a couple dozen .wma files sprinkled in), and most have a bitrate in the 192~320kbps range. Total storage size occupied by audio tracks = 60GB.
I also copied the entirety of my family's digital photo collection to the same drive. Total storage size occupied by images = 15GB.
Total storage size occupied on disk = 75GB. 1000GB total divided by 75GB occupied = 7.5% of disk occupied.
So, my first test was initial load time when connecting the drive via the USB drive. It took the system around 50 seconds to load the audio data (from moment of USB connection to audio being heard and USB audio screen displayed on DIS). Not fast, not slow; I can live with initial load times under a minute for 9500 songs.
Second test was response time between tracks when skipping to the next track in the same folder. This was very fast ... observably, just as fast as when doing the same thing with 10GB of audio data loaded onto my other 16GB flash drive. Excellent.
Third test was response time after engaging the "Random Track" feature. This was very fast as well. Very slight hesitation (maybe a second) was all.
Fourth test was response time when skipping to the next track with the "Random Track" still engaged. Very fast, again. Basically no hesitation whatsoever.
Fifth test was response time of the DIS menu commands for the USB folders in which the audio are tracks stored. I found the menu to be sluggish at times when moving from page to page of folders when in the root folder. (I have all my music sorted into sub-folders by artist, and to further sub-folders by album, so there is a lot going on for the system to handle). This wasn't unbearable, but rather, annoying.
Some other things of note:
- I noticed for sure today that the "random" feature does not randomize the entire disk's worth of audio. Based on my non-extensive, non-scientific testing, it seems as though it picks a certain number of sub-folders (at maximum) to use for the random playlist, and then also limits that playlist by track number as well.

Overall, I was impressed with the Genesis' ability to playback music from a large volume storage device with little headache. If you're the type of person who likes to have all their music on hand, have a huge library, and don't like lugging around CDs, then this is a neat possibility. Better if you stick to straight listen through with large volumes, as I've found the random feature becomes less useful the more songs you have.
Hows your 1TB hard drive working out? Still running good?
I haven't tried, but do .wav files work and if so are there any differences in operation? I'm trying to find a way that doesn't filter by name. It is tough to always start with "A".
