Just got my D3 installed and everything works perfectly, except the Nav Traffic option. When I go into the Navi Menu and select XM Status, it says the system is not connected and there is no signal. However, XM works on all channels so I know I'm getting a signal. I have spoken to XM several times and they've re-sent the Nav Traffic command to my system several times and still nothing (I am subscribed to Nav Traffic). Everything should be connected correctly as the installer that did the work is very very reputable and I trust his work. I have talked to him as well and he's not sure either. J
