Bose Radio/Navsystem and Mp3 tips and findings...
As I posted in other threads, the Bose Audio/Nav system seems to ignore Track Number ID tag in Mp3's stored on USB flash drive or my trusty "old" 80gig iPod Classic, or Ipad2 (with iOS 5.01) and instead play in alphabetical order of Track Name field. It doesn't matter if the actual file name contains the track name, like... 07-Bennie And The Jets.mp3
Since the 9-4x is similar to the Cadillac SRX, which is similar to the Chevy Equinox, which is similar to the GMC Terrain... I searched out forums discussing those vehicles and checked to see if they had similar issues, and how their owners worked around them... (and yes, the SRX with NAV has the same issues, I didn't find much talk in the forums for the Eq or Terrain)
This posting represents what I've found, and tested in my 9-4x with Nav in an effort to work around the track number in the ID tag being ignored, as well as no option of going Artist -> Album list -> songs... to play an album like I can on my iPod's built in menu system, and I could on my Dad's 2010 GMC Terrain's factory Pioneer unit without nav.
First up...
Using iPod Classic... (or iPad2 which is seen as an iPod by the stereo)
There is only one thing I can do to make the tracks play in track number order... include the track number in the beginning of the track name field.
Copying CD's to the Radio/Nav unit's hard drive...
CD's containing CD Text, or identified via the built-in Gracenote database, that you record to the unit's hard drive DO obey/follow the track number order when playing an album. However, Albums are listed without artist name, so if you have several artists with albums titled "greatest hits" you wont know which is which from the album listing.
USB Stick findings...
MP3's on USB stick, or copied to HD from USB stick do no honor the meta data for ID3 tag "track number" field,
To play in TRACK number order, the Track Name field must start with the track number, 01 - Hotel California.
Folders are treated as "play lists", but again do not honor track number ID3 tag field. They again play in alphabetical order of track name.
Play lists can be created as... Eagles Live CD1.m3u
containing list of tracks as Path\Filename.mp3 such as...
Eagles - Eagles Live (CD 1)\Eagles - 01 - Hotel California.mp3
Eagles - Eagles Live (CD 1)\Eagles - 02 - Heartache Tonight.mp3
Eagles - Eagles Live (CD 1)\Eagles - 03 - I Can't Tell You Why.mp3
Eagles - Eagles Live (CD 1)\Eagles - 04 - The Long Run.mp3
Eagles - Eagles Live (CD 1)\Eagles - 05 - New Kid In Town.mp3
Eagles - Eagles Live (CD 1)\Eagles - 06 - Life's Been Good.mp3
If you are a windows user, place the MP3's onto your USB drive, open a command prompt and change to the drive/directory constaining the songs you want on the play list.. the command... dir /b *.mp3 > playlist.m3u can be used to create the play list file (Replace PLAYLIST, with the actual name you want your play list to have.. example.. dir /b *.mp3 > Eagles Live CD1.m3u).
To make the play list in the ROOT of the drive.. dir /b *.mp3 > \playlist.m3u
To ADD songs in another folder to an existing play list on the root of the usb drive... change to where the next group of songs is, and use... dir /b *.mp3 >> \playlist.m3u
to make a single .m3u file with ALL songs from ALL folders on the USB card, place the MP3's onto your USB drive, open a command prompt and change to the drive/directory constaining the songs, and use the command... dir /b /s *.mp3 > \playlist.m3u You can now open Playlist.m3u in notepad and edit it/copy/cut/etc into smaller or other individual play lists.
Play lists and Folders show up under the same menu. If you make a play list with the same name as a folder, you'll see two listings on the Nav/Radio display screen.
Since play lists can point to any file/folder, you can make your own "best of.." play list and not have to have duplicate tracks on your USB drive.
The Nav/Radio unit will find/list HIDDEN folders/tracks. (I tried to make play list for albums and hide the folder in the hope that only the play list would show).
Conclusion...
If you want to have the unit respect ID3 tag track numbers, but don't want to load up the hard drive by recording audio CD's, one at a time, to the internal hard drive...
The best way to handle these limits appears to be forgot the iPod and internal hard drive... but instead use a USB flash drive with albums in folders named... Artist - Album... [example: Eagles - Eagles Live (CD 1) ] with the actual file name starting with the Track # [example: 01 - Hotel California.mp3, 02 - Heartache Tonight.mp3, 03 - I Can't Tell You Why.mp3, etc]. The Mp3 ID tags values for Artist, Track Name/Title, Album and Genre. (the Track Name/Title field does not need to include the track number) Then make .m3u play list files for compilation albums, like movie sound tracks, or "greatest hits of the '70's" type things.
After doing that, to listen to an album, go under Folders/Playlists, select it, and play..
Still to come...
- how many characters long can the folder names be (i.e. how many characters can the album's folder name on the USB stick be and still show all characters on the display?)
- How big can the USB drive be? (is 32gig the limit? The book says USB hard drive can be used, but what size? :D)
- The manual says you can pair BT devices supporting AVRCP (which my HTC Thunderbolt can do), but the phone can't pair in both Both "phone/handsfree" and AVRCP at the same time.. ok, so how do I do that with the car since my phone wants to pair in "phone/handsfree" mode FIRST. This would be neat to listen to streaming Rhapsody via BT on the car stereo (like I do at home) rather than connecting 3.5mm audio cable all the time. Or to pair my Moto Xoom or iPad for its audio to play via the car stereo while my son watches movies on it in the back seat)
