Hi,
This is the way i have been doing it form years, the easy way of getting it out is find the steepest hill you can find, and I mean steep, reverse as fast as you can and hit the brakes. Make sure you don't have anything in the area. If you have some one willing to lying the back at the vent this helps to catch it. Some times you need to do it 2-3 times. Has worked every time for me. Saves having to remove the seat and carpet.
PLEASE USE CAUTION when doing this.
Hope this helps.
Regards
