If you're installing a map to your stock BMW, it takes about 20-25 minutes the first time. This is because it first takes your stock map from the car and downloads it to your AP, then it installs the map you chose from the AP to your car.

If you're installing a new map over an old map (like going from Sport Map to Aggressive or Stock throttle to linear throttle) it only takes about 5-10 minutes because it doesn't need to download the map from your car at that point.
