More research and actually trying it has answered my questions. As

long as
you obey the allowable folder/file structure, the device should work.

This
is Kenwood's spec. fromhttp://www.kenwood.com/audiofile:


Maximum number of folder layers: 8
Maximum number of folders (per device): 500
Maximum number of files (per folder): 4096
Maximum number of files (per device): 15000


15,000 songs would fill 60-80gb in typical use! I'm sure flash will

reach
that capacity soon enough.


I now have a 16gb 2.0 flash drive over 2/3rds full and it reads with

no
errors (except DRM files synced with Windows Media Player 11 get

ignored).
The flash drive takes about 15 secs to load on power-up. As long as

you
don't unplug it, the last song position is remembered after you turn

off
the deck. Very convenient to not walk through folders again.


To be conservative, I'd group music into as few folders as possible.

You
can sort tracks in any order by naming them: 01 Song5, 02 Song3, 03

Song8,
etc.. Folders help with category sorting and navigation speed if the

deck
lacks ID tag genre sorting.


When the last file in a folder is reached, playback moves to the

first file
in the next folder, based on nesting levels and folder names. USB's

main
weakness is getting gapless playback to work outside a computer. For

me
there's no turning back to discs now.

Hi Tom,


I'm new to this group, and found your research very interesting.


I'm currently looking for a head unit that has both inbuilt DAB and a
USB port, and I didn't even think that USB Drive size would be an
issue.


I've got an old 40G 2.5" drive in a USB enclosure that I was thinking
of putting in the glove compartment, then taking the lead out the back
of the GC and then round into the back of the head unit.


Note, I'm NOT talking about what I'd call a USB thumb drive - this is
an old laptop drive.


From your research, do you foresee any problems with this setup?


Cheers

That would be best suited for decks like the JVC KD AVX33 that have
rear usb. Make sure your dash isn't in the sunlight, that heat will
cook a hard drive. Or at least shorten it's life. This is what I'll be
doing, like you, with the portable drive. I am going to cushion it and
put it under the seat, run the cable under the carpet, and see how long
it lasts. That is, when I get the aforementioned JVC.

Thanks for your response flak_monkey.

That unit looks fantastic, but it's probably a bit out of my price
range - I can spend only about £250 on this unit.

Also, I don't need it to play DVDs etc, which that one does, and I'd
rather have the DAB functionality built in, rather than needing an
additional unit.

(Re the USB drive - I was planning to store that in my glove
compartment - I've already tested leaving it there for longish
periods, and the case never seems to get too hot.)

Are there any other sub-£250 head units with integrated DAB and a rear
USB port?

Cheers
