I have had a Pioneer DEH-P7000UB headunit in my zed for the last few years and the two of us have got on very well together. I was using an 8GB Sony USB key for music storage, rather than keeping my iPod in the car. This worked well and would play both MP3 and AAC format files directly from the USB stick. I recently got to the point where I had more than 8GB of music, so treated myself to a 16GB Sony USB key. Having copied all the files from one stick to the other and then added a few more, I tried it in the car. I got a number of different messages, ranging from "Format read" to "ERROR-19" and occasionally the odd burst of music - I managed to persuade it to play one whole track, but it bombed out again on the next one.
Has anyone else had any experience with using USB keys (or USB hard drives) with Pioneer headunits? There are a few things that might be going on here, but it does seem odd that it will play any tracks at all, rather than all or none. So far my thoughts are:
* The headunit can't address the 16GB stick due to the size of the individual flash chips - this is true of certain types of camera memory card and also computer RAM - I didn't think it applied to USB sticks, but maybe it does
* The USB stick is faulty and has corrupted some of the files giving problems scanning the directories
* The stick is not flat formatted - the last one had some Sony software pre-loaded onto it - this one didn't, but could it be lurking in a hidden partition?
Before I can it and start getting selective with my listening, does anyone have any ideas?
