Have anyone experience that the mp3 song got cut off in the last few second before the whole song end?
for example, the song should be 3:45 mins long, but it will cut off and move to next song at 3:30mins.
It happened to some of the mp3 songs, but some other were fine.
The song play perfectly in computer tho.
I'm using 8gb SDHC card to store the songs.
Anyone know how to fix this problem?!
I have had the same issue, only with a few songs on my SD. Not sure why they do it.
This happens to me on atleast 25% of my songs. I have tried a 1GB SD and a 8GB SDHC with the same results. I have noticed the 8GB loads much faster even though it has about 4x more music than the 1GB, but it still skips frequently. Today I had a song skip about halfway through with over a minute to go. I'm very annoyed with this, more so than the long boot times as I only have that happen once each time I start the car.
I've just started to have this song ending prematurely. It's(f700bt) been working flawlessly for about a month.
I think the mp3 files are fragmented or something.
Same issue on my 4GB USB and 2GB SD. Songs are cutting off 2-5 seconds early on about 90% of the files. They work fine on my pc. I've just learned to deal with it until I get an Ipod (god I hate that word)
Same here..songs frequently cut off a few seconds before the end of the song and occasionally cut out for a second or two in the middle of the song..seems to be getting more frequent over time.
I used to be a diehard Pioneer fan but I am now starting to question their quality.
I highly suggest you guys get an iPod!
The VR control alone is worth it and I have not had any problems playing any songs.
Please don't flame me, just trying to help 
Same here....
And it's like that since the beggining... Pioneer should put that in the bug fixes for a future firmware release (IF they still care about this product...Unfortunately im afraid they think their last firmware update was good enough...).
When i bought the product, i wanted something that could play easily my MP3s, not something that would force me to buy an Ipod...
Anyone on the thread using Windows 7?
Cutting off the end of MP3s is a known bug.
Just making sure no one misses it.
Not using windows 7..XP here and the same files on the same media play till the end with no issues on the PC.
same issue here, maybe 10% of the time. mine are loading from a 16 gig usb drive.
if i remember, i'll check to see if a track that cut off early does the same thing the next time it is played.. unless someone else already has tried? at least that would determine if its file related or random files.
Sounds like it could be a codec issue. Try ripping the MP3s with different SW or using a different bitrate.
I logged on today to see if anyone else has this problem.
I have noticed that music encoded with the LAME MP3 encoder do this vs. the Fraunhofer encoded music plays to the last second. Not sure why... LAME is supposted to be one of the best encoders for MP3.
I play the same files on my Samsung Omnia (Windows Mobile 6.1) using Windows Media Player and it plays to the end with no issues.
heh.. figures that it would take a long time to find a track that cut off.. it is a VBR mp3.. i don't have many VBRs, i typically rip @ 256 or 320 kbps, and usually re-encode any downloaded vbr files... can someone else confirm that VBR mp3s are the source of this problem?
info that might matter to the f90bt when reading the header:
Encoder Delay: 576
Zero Padding: 1296
230kbit (VBR), 7321 frames
All of my MP3's are VBR. But only the LAME encoded files get cut off.
i typically rip @ 256 or 320 kbps, and usually re-encode any downloaded vbr files...
what you just described doing is called transcoding and makes your songs sound like crap
if you download variable bit rate mp3 and encode them to a flat 320 or whatever youre transcoding and ruining the sound quality. try to get it in the format you prefer, or if you can't just get FLAC and burn it to a disc and rip them that way.
but DONT UNDER ANY CIRCUMSTANCES re-rip something unless its FLAC
just a tip for sound quality

yeah.. i'm very aware of the negative effects of transcoding. although i avoid low bitrate and vbr mp3 files most of the time, once in a while i'm only able to find an album in vbr. in those rare situations, i'll take what i get. i have an old sansa mp3 player that doesn't support vbr, so for years i've had to convert vbr mp3 to a standard bitrate. i definitely prefer to *not* do this. once i find a better copy, i do replace the transcoded files.
in regards to flac, i made a decision a long time ago that the only time i'd keep flac audio files were for bootleg concerts, whereas cd albums sound "good enough" as mp3s. (keeping in mind that the only time any of these files are played are in my truck on the f90, or on my old sansa!)
thanks for the tip for others who don't know though!
I'm a new F90BT owner who's library must be half LAME! About 50% of my MP3s get cut off when played via USB or SD card in this unit. I went to the store where I bought it and tried it in an AVIC-F700BT and another f90BT on display and both cut off on the same songs. Looks like a design flaw or shared SW bug. Interesting to see that one of the Pioneer non-NAV models plays the songs OK off a USB thmb drive. Must not use the same SW or design.
Sad to see that the MS software in an expensive unit like this would have such a problem and not get fixed. makes it unusable for me.
I returned to the store and they've agreed to take the unit back. But I got them to agree to wait until the new models show up in a month and we can try those out and they will still honor my 30 day satisfaction garantee. I'm hoping this got fixed in the new line. Otherwise It will be time for another brand of NAV for me.
It would be nice if a Pioneer rep could verify if the MP3 cutoff is fixed but I've found no way to get them to respond so far.
bump i just started noticeing this 
ok so i looked at some of the files that skipped and some of the files that don't. i dont think LAME encoder is to blame. some of the files i have that do not skip are encoded with LAME in VBR and they play fine. i only recently started seeing this problem after the 3 gig mark on my SD card
Haven't tried myself - and it's just an idea...maybe the "allocation unit size" being defined for a SD card during the format could cause this problem?
I'm talking about THIS format dialogue on the pc:
Try to use different sizes to see, if this could cause/solve the problems.
I don't know exactly how media like USB sticks or memory card work, but on hard disks everything is managed in so-called blocks. And if the AVIC reads block-by-block (e.g. 8KB blocks) and the unit size of the SD card is organized differently, then it *could* be a reason.
But like I said...just an idea. Don't have time to check it now, because my TMC isn't still working (and the cut-off of the last seconds from the SD card (I do experience also on my 8GB SDHC Type 6 card!) is priority 2 
Hello everyone,
I am having the exact same issue. My MP3s are getting cut off on my Pioneer AVIC900BT. It does not matter whether or not I am playing from a flash card or through the USB connection to the AVIC. They both cut off.
I have not experimented or trouble-shooted the problem too much. Most of MP3s are ripped with the LAME encoder using VBR. I have some MP3s that were purchased from EMusic, which I think we ripped with a different encoder than LAME. It does not seem to matter which encoder was used. The amount of time that is cut off of the end of the song does not seem to stay the same. It varies greatly.
My songs are starting to get cut off about 70% to 90%, depending on the album. It is driving me crazy!!
I love the GPS navigation part of my unit but I hate this issue. I think this qualifies the unit as defective.
Interestingly enough, when we hooked up the IPOD through the USB connection, it refused to play the audio through connection even though it acted like it should play.
I called tech support and I am sending the unit in for repair. They act like they have never heard of this issue before, which seems crazy since everyone here is experiencing the same issue so it means it is a wide spread issue.
There is another firmware update coming out in June / July, which I confirmed with tech support, v2.006 or something like that. [just confirmed it]. Has anyone tried this? Does it fix the issue?
Does anyone have any other ideas on what to check?

UPDATE: Mid August I got the new x910BT unit with 3.0 firmware and the song cutoff is cured. The remianing problem is that USB/SD MP3 support for more than about 600 files is very unreliable. At 1200 songs it takes 5 minutes to boot up teh SD card, then hangs the unit between songs, especially in random play mode. I'm hoping the Pioneer or MS folks read these forums and work to fix this problem. An expensive unit like this should handle 50k MP3s just fine.
