I just got my 8000 in today and so far I am liking it. It is just powered up on my bench, not in the car yet.
When I was running through the nav setup wizard it has a screen saying something about being able to activate the connected online features by connecting to a suitable WiFi network. I know that the 8000 doesn't come with WiFi built in but I wonder if it could use a USB WiFi adapter. I don't have one to test with though 
Does anyone know if that is waht the AVICSYNC app will do if they ever release it?
On a side note I like the look of the maps better on my Garmin but I like the interface better on the 8000.
