I'm getting ready to purchase a FIT and wonder if the stock NAV/Audio unit is worth the extra $2,000? I of course have an Ipod and when I looked at the car recently it appeared that the audio unit did not control the ipod, which it seems that any decent unit now a days would. I do like the voice control feature...I do like having the controls on the steering wheel. I know you can get a good Aftermarket one for $1200-$1500, but then having it as slick as the stock one with steering wheel controls might be an issue...
