Hello, I have the N4 for about a week, I installed myself. That turned into more work then I thought it would be. When I first installed the unit I did so with the reverse camera and a cd changer. Yesterday I went to the store and purchased the blue tooth, ipod wire, and sirius. This baby is fully loaded now! Everything is working great. I have 1 question in reguards to the Sirius traffic. When I select the traffic source it goes to Sirius with channel 148, which is NYC traffic, however i get no sound. Whats wrong? I have the Sirius SIR-PNR2.

Its like a preset button. Figure out what channel number your city is for traffic info. Go to that channel and press and hold the traffic button and it should store it

Wow, I didn't know that. Mine just turned to channel 1 when I pressed traffic. Never looked into it. I gladly welcome anything that can be used as another preset with sirius. With local radio, I could never find even 6 stations I would listen to.
