Just updated to 5.4.B.R8 no problems, only sometimes error on "no music files", but that has happend due to incorrect file structure. correct to other layout works fine. include also the new map 2016-1 and this one work also fine.
so thanks to all for make this happening.
only is somewhat irritating, the noise from the system to indicatie a blinker and no option to change this.
has the C4 Picasso 2014 Exclusive model.
By the way updated on a stick of 128 Gb formated as FAT32 and the system just eat this as cake. i have normally the music files on this one and have a space of 128 Gb of music. jukebox works fine and continue on the spot it stays when turned off.
adaptive control works now a lot easier and has adequate speed to some reactions if needed.
