On the right of the audio source line at the bottom of the 8000 navigation screen there is a car with an arrow that points up and one that points down. One press turns it green another seems to turn it off. Not sure what this is for. GPS? Sync? Can't find where this is discussed in the manual. Anyone know?

This is for AVICSYNC app that will come out for the iphone and Android phones. This will give you live traffic updates, weather, fuel prices etc. when connected to your phone

Thats what I figured. I hear that its a subscription. Have you heard how much it will cost?

Details haven't emerged on price. I'm assuming it will probably be between 60-100 per year
