I wonder if the 2k1 fostered any of the new relationship with RF? Granted, the audio from Rockford Fosgate in our 2k5 isn't the best, it is far better than a Ford Ranger/Taco or any Chevy/Dodge midsize. Funny it has the same number of speakers as the Altima Bose solution.
Controls are VERY similar, only irration on the steering wheel is they replace the odometer button control with power switch for the radio.... I hate having to push the button on the dash to look at mileage...
