Last night I got an E-Mail from E-Ten regarding a "new" ROM (version 0171) for the E-Ten M600 Windows Mobile 5.0 Pocket PC Phone Edition, E-Ten is providing to the media but the ROM isn't anything secret at all, it's even not that new (but from 26th December last year). Therefore it's already available from several E-TEN distributors.
ROM version 0171 contains some major radio improvements and fixes but is still based on Windows Mobile 5.0 AKU 1.1 which - as we know - supports Bluetooth contact synchronization with car kits (see my previous review here) but not Bluetooth stereo
through the A2DP profile.
While the two most important ROM updates, E-Ten provided so far were the ROM versions 0161 and 0170, which fixed at least the following issues (from ETEN Pocket PC User Forum):
- Added GPRS modem by USB
- Added Voice Commander through Bluetooth Headset
- Fixed CALL log IN/OUT/Miss icon in Today screen go always to Missing calls
- Fixed Remove SD card from M600 lag in Explorer
- Fixed 40% turn on WIFI and unable to turn device on, only turn on when you put it back to AC power
- Fixed STD
- Improved in Bluetooth GSM quality (distorting)
- Fixed Backlight can't turn on after sleep mode
it seems that ROM version 0171 also adds the Bluetooth A2DP and AVRCP profiles and this without having Microsoft's AKU 2.0 on board. Even more interesting is the fact, that the propriety Bluetooth manager even not informs you, that the (A2DP enabled) headset you are going to pair with the M600 supports A2DP stereo profile but it just pairs like a "regular" headset:
However, for a short time the headset icon with the note icon in between appears in the task bar and stays in the connectivity bubble and from the AKU 2.0 we know what it means: Bluetooth stereo support!
That's a clear indication that the connected headset is seen by the device as an A2DP enabled stereo headset. Therefore the next test is to verify it with the Windows Media Player on the E600 and guess what happens: no more system sounds from the device's inbuilt speaker but all the system sounds comes through the headset , including the music playback from the Windows Media Player:
And yes, the E-Eten M600 Bluetooth implementation also supports the AVRCP Bluetooth profile to remote control the Media Player which includes pausing/resuming playback as well as jumping to the next/previous song in the playlist.
So the E-Ten M600 is the second device with Windows Mobile 5.0 which supports Bluetooth stereo even without having the (according to Microsoft) required AKU 2 on board. The first one, I was aware of is the T-Mobile MDA Pro (HTC Universal) which is also Bluetooth stereo enabled after the latest ROM update from last week.
However, while the Universal is a little bit bulky to carry him as a MP3 player, the M600 is just perfect!
