Sorry for bump, but I just bought my AP recently. After looking at a bunch of AP mounting positions for inspiration, I ended up trying this instead.
Very simple, and haven't seen any one else do it yet.
IMO, the most intuitive method as it makes it seem like it's part of your cluster.
No mounts required, I just lowered my steering column, placed the AP in that spot, and then tilted up the steering column until it "clamps" the AP in place.
Sure, you'll loose out on some info like your fuel tank and mileage, but that's not really info you need to keep a constant watch during your drive.
