Yes, I use a 4GB ADATA 150X Hi Speed card that I bought on eBay every day.

The limit is 512 files plus folders (a folder counts as a file).

At an average of 10 files per folder: 460 files + 46 folders = 506.

ummm, does that mean you can use 4GB of space though?

Yes, you can use the whole 4GB (ok a little less but almost 4GB) if you format the card with FAT32. My 4GB is about 3.5GB full and I used it every day.

Corrupted Data Issue...

I was wondering if anyone else has seen an issue like this...I bought a 2GB SanDisk UltraII card from Best Buy....figured I would test with this one since it is easier to return, not the 4GB ADATA 150X Hi Speed I ordered from eBay :) I put the card in my reader loaded it up with about 2GB's worth of MP3's (19 Albums/Folders @ 256Kbps)...put it in the unit (B7 RNS-E - 2006 A4 S-line w/ APR chip) and it showed Data Corrupted...so I brought it back inside and sure enough the disk was corrupted...so it asked if I wanted to Format the disk, so I quick formatted with FAT32, put one Album/folder on there and tested it and it worked? Now it will only show up as a 1GB card...wondering if anyone has seen an issue like this? Let me know, thanks.

Could be your computer. Some have reported that older flash reader/writers do not work well with flash memory above 1GB. If you are using an older flash reader/writer this could be the case.

Have you tried a full format, not a quick format?

Quick format just rewrites the root directory, so any other corruptions will remain.

I think you are correct

I tried the built in card read on my HP nx9600 laptop and it saw the entire 2GB...the reader that I have at home is a bit older and did come out prior to the existence of the SD Ultra cards and higher capacity...so I assume that was it. I am going to buy a portable USB reader later tonight...thanks for the good suggestions.

To read/write my SD cards I use a Lexar JumpDrive Trio that plugs into any USB port on either my laptop, desktop or work PCs. It's always been 100% reliable for me.

On my iMac I have problems with the MP3 Files. As soon as I copy then on the card, MAC OSX makes some hidden Files and the RNS-E says “Data Corrupted...“ When I delete those on my Windows based notebook it works fine.
On the Notebook I always use Panasonic SD Formartter http://panasonic.co.jp/pavc/global/cs/sd/download/sd_formatter.html . With this program You wont have any problems.

Where's the 512 file limit from

I have an RS4 with Nav+ due for delivery in June :D and like most of us here have many gigs of tunes. Currently using Dension iceLink for my iPod against Concert radio in S4 I have.

Anyway, 4G should be able to get me something over 750 tracks (AAC but MP3 is bigger so maybe less) but where is this limit of 512 coming from? Is this a limitiation of SD standard (would surprise me given using FAT32 as format and that isn't 512 limited) or is it a Nav+ firmware limit?

Anyone heard of just pluging in a 20G+ USB drive or something into the back of one of these babies and having it MP3 navigable (id tag etc) just as if it was a huge SD card.

There is a new SD spec for 28G - guess Nav+ can't handle that.

cheers,
- Dean

The 512 items limit seems to be RNS-E software related and is not caused by SD standards. The hope is that a future RNS-E software update will remove this limite.

There is a USB2CDC blackbox available in Europe but it's currently limited to 2GB media, FAT 16 formatted. Since the CDC port doesn't support ID tags, more doesn't make much sense unless you have a phatbox or can see the device's display.

Besides that, Dietz is rumored to develop a USB2??? device that uses the FIS/DIS to display the song name ut there are no other details available at this time. And there is the 3pmdev.de project that still looks promising but is not available for the RNS-E yet and very expensive.

So if you can only have 506 (or about that) many files, there's no point to a 4GB SD card, being it will store about 1000 files. Is that correct?

Unless you rip with 320k or have fewer but longer songs there is no advantage over having multiple 2GB cards for less money.

So you don't think brand for the SD card makes a difference?

Forgive me as I am a MP3 virgin!

So I can buy MP3s online, download them, then burn them to a SD card on my laptop. Then put them in my NAV and whola??

Thanks in advance!

4gb cards can be useful

if you stick all the tracks of an album end to end as 1 big mp3 file then you can load lots more albums onto the card but only useful if you tend to listen to whole albums through from start to finish - good for pink floyd for instance!

dont forget that the current firmware cant play variable bit mp3 files - you have to convert to fixed rate first
