PDC questions

[theprof]

I have an 08 X5. Love the thing; but the PDC just isn't working for me. It takes too long to start up; I'm already backing up before the couple seconds passes for the screen to come up. Also stays on WAY TOO long blanking the screen to other apps like Navigation or whatever. The PDC staying on for 160 feet and x seconds or whatever seems to be the way its supposed to work - but I have no idea why; don't need to see where I've been. And of course the camera sucks and is of little value at night. I find now, after 4900 miles that I hit the "off" for PDC immediately after putting the X5 in reverse.

My Questions:
Can any of this be controlled?; how fast it comes on, making it go off immediately after shifting into Drive? Maybe a software update or something?

Assuming there are no fixes (which is what I assume) is there a way to just turn PDC off entirely?

The PDC and the TPC systems are the only things I find really disappointing about the vehicle. Otherwise its a great rig and all that technology is quite useful and nicely integrated.

Thanks,
