Recently purchased SMH10, using it on the BMW K1600GT, wonderfull and incomparible with the BMW BT system (SMH10 much better...) :-)
Connected the SMH10 to an Iphone 4S and the BMW audio system, nothing paired to the BMW NAV4(Zumo660)

When receiving NAV instructions the audio is muted, when receiving NAV speedtrap warnings audio is muted but the warnings "beeps" are hardly heard.

? Can the muting level be changed individualy (audio higher/lower, Nav higher/lower)
? Can the volume level of the speedtrapwarnings be changed?

SMH10 still on firmware 3.3 as advised by my supplier because of "known" icompatibility of the firmware 4.0 in combination with the K1600
