I just had this recently (2 days ago). I found a thread on another forum that helped out, here's what I did:
1) Power Off using touch screen and let it sit for 5 minutes.
2) After 5 minutes power back on using the brake, and then power cycle using brake and both thumb wheels.
3) Power cycle again using brake and both thumb wheels.
After I did this the car had reset the download and everything went smoothly. Hope this helps
