Slow CPU start-up screen time?

I've noticed that 9 times out of 10, when I start the car, the idrive screen takes about 15 seconds to boot. I see the BMW logo for 15 seconds, then the "accept" screen comes up. But what the problem here is, is that when you back up the car, you don't see the "radar" screen either. The "radar" screen comes up when I've already finished backing up, and am moving forward. When I'm in for my 1200 mile service, I will have the dealer look at it. Maybe a software upgrade would solve it.

Has anyone else experienced this problem? If so, how was it fixed.
Thanks

Same thing happens to me except mine takes longer, by the time the PDC comes on I have already backed up and driven off. I consider this a minor issue and don't worry about it too much.

Yeah, but......
It shouldn't be that way. I use the PDC often in conjunction with my own eyes. On my 2003 745Li, the PDC came up instantly when the car was put in reverse. Same should occur on the M5. Otherwise, why bother having the PDC? One could always manually push it when backing up, but, I'd prefer it coming up automatically. Just my preferance.

This irritates me everytime I back my car out of the garage in the morning. I think the PDC should override the disclaimer. In my opinion this is a safety issue. The PDC should pop up right away when you put it in reverse. I know I could wait 30 seconds for idrive to boot up, but I'm impatient!

Also, how come idrive sometimes pops up right away but sometimes takes up to 30 seconds to load? It doesn't seem to be dependent on how long the car has been sitting. I gave the car a day off and the next day idrive came on as soon as I started and today after I was in the bank for 5 minutes in took about 20 seconds to come on. What gives?

My "accept" screen usually comes up in the time that it takes me to fasten the seat belt after starting the car. Infrequently it takes a little longer. Even when the PDC screen is not yet available, the PDC provides its audible signal.

I agree the delay is annoying.

I also wonder about the dramatic variability in the delay. I have a theory, but haven't done any controlled testing.

I suspect that the car may "wake up" when it "sees" your comfort access FOB, so walking near the car, but not getting it right away might give it time to wake up.

Do people without comfort access also experience variable wake-up times?

Yes. When I put my laptop case in my trunk when going to/from work, the computer is ready to go when I start it up. If I jump right in, it takes forever.

Well, I see by the posts so far that a few other M5 owners are experiencing this problem. The point here, is that this is a PROBLEM. This is not how it's supposed to work. We should all be going to the dealers to complain and ask for a solution. The PDC should come up the moment you put it into reverse. After your driving in a forward direction for a while, the PDC screen goes away and THEN the "accept" screen should come up next. That's how it was in my former 7er. I will check with my dealer and see what they can do. I'm due for service in about 2 weeks (1200 miles)
