You definitely need fat32. I don't know if you'd want to hook up an external harddrive, but it might be possible. The interface for usb isn't the greatest and the order of music would be in order it was written to the hard drive. For a large collection it is pretty tough to scroll through. you can't sort by artist albums or anything. I hooked up a 2 GB flash drive that had 10 albums and I didn't like it. Unless you were to shuffle all or listen in the order they are written it would be fine, but a larger collection would be very hard to scroll and find anything specific.
I've tried a 4GB Kingston thumb drive formatted FAT32 and it worked. I am not sure if the USB port has enough power to run an external HD. Besides, why would you want to bounce a HD around in the glove box, it would eventually crash the HD (unless you put suspend it somehow and not overheat it).
I as such have lots of albums and wanted to fully use the USB feature and had the albums/tracks organized properly. It is one thing that the tags work weird on some but alright on others. A totally different and more disappointing thing is, I bought a passport drive (100GB) in hopes of dumping all my music and use it. The honda system does not even recognize and gives error. I am pretty disappointed.
Anybody has some luck getting a Passport disk to work ? I have no problem using the simple flash drive...
Did you format the drive to FAT32? If so, I'd agree that it doesn't have enough power. Sometime a shorter USB cable will work, but in this case, the cable from the glove box to the navi would be in addition to the size of cable you use and wouldn't make a difference.
Yep, I formatted my 2GB flash drive to NTFS and it doesn't play the songs. I had FAT by default but then it does not support more than 131 songs. I am going to try FAT32 and see if I can get more songs that way.
