I have recently taken delivery of a new mark 3 jazz. While driving I like to hear the Traffic Announcements, but find that each time an announcement comes on, I have to increase the volume control to hear it comfortably. On previous cars, including earlier Jazz's that I have owned, the TA announcement volume is set at the level that it was set to on the previous announcement, instead of reverting some default value. The handbook does not appear to offer any help. If anyone has any ideas on this, I would pleased to know them. Thanks in advance
