Mine was under the spare wheel.

Do you have air or spring suspension on the rear?

Unfortunately, i have Air sus in the rear.

That's what I thought, until I loaded 20 bags of concrete into the boot and she trucked on as if nothing was amiss

Your is a V8 so it should also have Air right?

Yeah air in the rear and coil overs in the front.

z168 - maybe take out the spare wheel first and check that it's not there like Tymatyk's as if it is that'll save you a lot of dicking around

I just got my 4.8is not too long ago and the PO had a backup camera on the license plate mounted. I've noticed a couple of things and I want to know what's the norm or fix.

1. When my vehicle is off and doors closed, screen is off (as it should be). When I press the unlock button and open the door, the screen "comes on" but nothing is displayed. It does shut off though eventually if I don't actually start it. I was told this is normal. I would have thought normal would be that it came on and the BMW logo would show.

2. Whenever I put it in reverse, the screen goes blank. Meaning, I'm driving with the radio on or whatever, then put it in reverse to back into a parking spot or my garage, the screen goes blank. It looks just like above. It's technically "on" but nothing is displayed.

So I'm thinking that the camera has to be connected, otherwise it wouldn't go blank. It just may be connected wrong???

Thanks. I will do that. I will take pics as well

So do I have it?

Was snooping around in the spare wheel and found that mine is actually under the spare wheel as well, was mistaken with something else under the nav stuff.

You need to remove that bell housing (air pump housing) and its in under there

The silver box on the left is something else - what you're looking for is next to it, you don't need to remove the battery but you do need to remove the casing - it is held in with 3 phillips head screws
