I have the Sirius PNR2 in dash satellite tuner connected to my D3 and was wondering if they make a different Sirius tuner to allow the Nav/Traffic function. I drive quite a bit in the LA area, and this would be a big help in avoiding accidents and what not. Thanks again in advance for any insight on this!

Nav Traffic is for XM subscribers only... well as of now, they are planning a merger so this may change if the merger happens.
