Can't pair iPhone on 2005 BMW x5

What phone is it? Is it an iOS phone (iPhone) or an Android phone (anything that isn't an iPhone)? Try this.
First go to the bluetooth settings on your phone and turn it on. Next go to the 'Visibility' area in the bluetooth settings and turn that on.
Go to the phone settings in the car and search for your phone. Sometimes it does take a few attempts for the phone and car's bluetooth to find each other.

You'll have to confirm this with BMW as we have a 650, 135, and X3 not an X5, but your car won't play iphone based music via bluetooth. It will sync contacts, make calls and some other things (particularly with the newer apps) but it won't play your music.

To play your music you have to have the package that allows you to connect your iphone via an iphone cable (usb at one end, iphone connector at the other - what you use to charge it). With this connected you can then see all your music and control your iphone through the screen on the dashoard.

Key-in, Ignition On (but don't need to start the engine)Press the R/T button on the steering wheel. "Activate Phone" should display on the radio. On the iPhone search the BT device. Select your car and enter the passkey when prompt on the iphone. Make sure there is no other BT phone near-by or the old one that has paired with the car previously. There is also the maximum number of devices you can have in the BMW BT sharing. If you reach the max, you may have to clear the car BT pairing memory by removing the power to the BT unit (by removing a fuse in the rear fuse box). The info is in the manual and inside the fuse box (which tell you which fuse is for the BT.)

If the BMW system is like my system: I found I need to select the phone, then delete it from the system. Make sure your phone Bluetooth is set to on, and available to other devices, then set the car to look for, or add phone. It should find it, then once again, if like my system, send a code to the phone which you need to OK for it to work.

i've had the same problems in the past with an old HTC and my blackberrys Acura tells me the phones aren't compatible. One will find the other and not pair so i started making the car and the device search at the same time, after 4 or 5 tries consecutive tries at that they have all finally paired. -My current Blackberry needed an update for this to work.

That BT is NOT compatible with iPhone, it is that simple, you must get a compatible one.

Hi , you will need to find out wether your phone is compatable with your car, depending on the country that you live in you should be able to log on to a B M W web site that will give you compatability. regards mark.

some phones do not work with the bmw systems please check with your dealer which phone works on your model

carry out a battery reset and this is done by disconnecting the battery for 10 mins.

i use to work for honda and acura and from what i recall, the iphone is and or wasnt compatible with the bluetooth sytems(factory) i was haveing trouble pairing a custs iphone in a pilot, then was told its not compatible with that phone
