Tried 100 times ... iPhone can't see my car . MSG on idrive say " car mobile not installed ". !!!!! Need help

I think what you are asking is how to connect the headphones to the iphone via Bluetooth.
switch on the headphones Bluetooth....go to general settings in iphone ... Switch on iphone Bluetooth....then choose detect devices....when it finds the headphones... Click "pair" ...it will let you know if pairing was successful.once it remembers the device you won't need to do all that again next time you want to use the headphones.now and again you will need to charge the headset up.

Hi Bob,

Once you pair your iphone with you car's bluetooth system, it should remember it the next time, make sure you do this through your vehicle's radio system rather than your iphone, although you will need to enter the code from your iphone into the car's bluetooth system.

did you mean via bluetooth? if yes please remove saved car kit devices from you phone and then try again with correct pass-codes

make sure your bluetooth is turned on by going to settings>bluetooth

Make sure that your phone is discoverable, it is amazing how many people dont know that you have to make your phone discoverable for the device you are connecting t to be able to find you.

If it is and works with other devices it may be the BMW version of bluetooth. Just like every other piece of software and hardware newer bluethooth versions are released as time goes on.

As I understand it, Bluetooth on older devices run on a different version of bluetooth to newer devices. This is most often the issue when someone has sync issues. So newer devices will find or link to older ones but not necessarily the other way around. One of my jobs is driving all types of cars and I find that older cars have issues syncing to my iphone than newer ones.

All I can suggest is to try syncing an older phone or device to your BMW just to ensure there are no issues with the BMW connection.

Delete the (bluetooth)? connection then reinstal.

Make yours car bluetooth visible when trying to pair with phone

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.)

Hi
I have just paired my Iphone 5 with the Hkt300.

I used the code 0000 while holding down the button on the car set.
Have fun
John

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