Re: New 159 Lusson sportwagon (Blue&Me problems...)
As most have said, B&M is pretty good.
I too have q-tronic so I'll look forward to the stick coming off!
go to your car without your phone on at all. sit and use setting to delete all user data. then get your phone started and re-pair the two. should help.
as for the media player, get a second usb drive (a cheap small one with just 2 or 3 tracks on it) and place that in the usb socket, then when it plays those tracks, replace it with a larger one, it will rebuild the music list.
There is a possibility that you have some wiring issue with the steering wheel buttons as all the functions you have issues with can be recreated using those buttons. if thats the case, then back to the dealers where you'll find the knowledge level about B&M scant to say the least.
