i have a 2002 m5. when i have the nav volume set to "max", the volume of the the directions is a little softer than the radio volume into which it cuts in. if you have it anything below the max setting, it is completely inaudible. i took this back to my dealer and i was told that this is the way the new nav systems are and there's nothing that can be done about it. as if it were god speaking, they said the "regional" representative looked at it and agreed that nothing could be done. this makes absolutely no sense to me and i don't buy it. has anyone else eperienced this problem. is this a software glitch and, if so, could we petitiion as a group to get it fixed. any other suggestions. also, was this an issue on the older nav versions. many thanks in advance - jf
