MMI 2G/AMI very slow USB file load

[Duffy]

Hi

I've just been through the whole firmware upgrade process with this and it's now on the latest firmware. However in general use I see that loading music (apple lossless/Mpeg4 files) from the USB stick (a 64gb stick recommended by someone else on here) it takes 20 seconds to load and/or buffer a song before playing.

Is this normal or perhaps caused by the size of the stick?

I can stick a Ipod or use the CD changer and it's immediate when playing.

I've got B and O so I'm keen to stick to uncompressed files as the difference in sound quality if very obvious with lower rate files.

Any thoughts?

Thanks!
