well, i too have a couple of niggles, perhaps you can help?
Firstly, when i plug the USB drive in for MP3s it doesnt keep playing the songs in any order, just repeats the same song unless i forward the track manually?
Also, should my alarm beep twice (with a small pause between them) when i lock the car? or is that a fault?
I find the nav ok, but would be better if i could use post codes, and i havent had the same success with you for the voice recog - we fall out quite regularly.
but otherwise pretty happy.
For the MP3 issue Blue&Me's database of songs has got messed up. Pop any other memory stick in there and turn the car on, it will build a new database for that memory stick. Now put your original stick in and it will build a new database again, this time it'll be all working. Can also be fixed by disconnecting the battery.
If you don't have another stick just copy all your music onto your PC and pop one random MP3 on the stick, put it in let B&M build it's library and then put all the music back on and let it create the correct database.
It's a known fault with B&M but thankfully doesn't happen that often. You'll find that once you've fixed it you won't see it again for months/years and then all of a sudden you'll need to rebuild the media library by changing round drives.
As for the alarm beeping twice, not sure if it's the same as the Bravo but if you push the lock button once you hear the car locking, pushing the lock button twice quickly will lock the car and engage the deadlocks which gives the impression of two beeps/noises. It's become second nature for me to engage the deadlocks now as I always push the button twice.
Can't help with the B&M Nav as I've not go it, the voice thing started out hit and miss with me. I've 'learnt' what she likes and what she doesn't now which helps. Spelling contacts how they should sound and using special characters such as the e in Zoe with an ' above it helps. Pushing the button and saying 'Playlists' 'Artists' 'Play Something' 'Shuffle' all work perfectly now as does names I know how to pronounce to her. 'Call Sammy' always works where as 'Call Haydn' sometimes brings up 'Home' and 'Home' sometimes brings up 'Haydn'.
EDIT: Drive must be FAT32 (B&M won't read NTFS) and it has been known to have issues with big drives (although my 16GB USB drive has been fine after I originally got it setup). People have been known to keep a 32mb old USB stick with one track in the car just in case to swap over and refresh the library but I think that's overkill tbh.
It won't matter if you have MP4's or any other documents on there as B&M just skips past them, doesn't really matter what folder structure you have or where Playlist files are either as long as the path directory isn't longer than B&M and FAT32 can handle (Don't know the limit off the top of my head, 64/128 characters maybe?)
