    Pre-CAN Bus Audi's and VW's use what's called the GALA wire for speed sensing on their nav units.

    There are a couple places you can get speed signals. Off the top of my head I think its the green and white wire but check your bentley before tapping. You can find it 2 places behind the dash. The first place is going to the back of the instrument cluster in your dash.... kind of a pain to get to.

    OR, the easier place: One cool VW/audi feature is the speed sensitive wipers. Behind your lower dash once you locate the wiper relay you will also find a VSS line going to it. You can tap that line for your navi unit.

    Dont most GPS units tell you your speed from the satelite? So why would you need to find the speed sensor wire for your vehicle?

    Some use it as a double check. That is how the Prius can tell you how fast you are going even if you are drivng in a tunnel!

    Some also use it as a more secure way of knowing if the car is stopped or not to allow you to enter an address and stuff.
