New X5 owner - Lots of questions

[gregorio]

Hi everyone - I just purchased a pristine 2004 X5 4.4i with 88,000 miles. It was a lease return that was really pampered. They even detailed it before they returned it! This is my second BMW after being a MB fan for decades. I am liking it a lot there are a few quirks that I am hoping everyone here can help me understand.

Options are; Premium Package, Rear Climate Package, Sport Package, 19" Wheels, Park Distance Control and Navigation.

First, the Park Distance Control seems flakey. It did not activate the first time I parked it but after backing up and trying again, it instantly went to full scream. No beeps. Also, after putting the car in PARK, I expected it to stop screaming but this is not the case.

Second, it looks like it had a mobile phone installed or at least the prep package. What is confusing me is that I have a laminated card with a Blue Tooth PassKey. What is that? I thought it means I could pair my BT phone to the car but after reading here I see that I would need an updated ULF (wahtever that is) module.

Last, what recommendations do you have for iPod connection? I bought one that took the place of my CD Changer in my 2006 325 Ci but that is not somehting I'd like to lose in this car because there is no CD in the dash. Do later Navigation units have a CD in dash and AUX input? Can they be swapped in?

Thanks in advance for all your help.
