X5 E53 2006 BLUETOOTH ISSUES WITH IPHONE 4S

[corse748b]

Hi All

I have just purchased a 2006 3.0D with TV/RADIO/SATNAV Dash unit.

I have also purchased all of the trays and snap in adaptors for the Bluetooth facility for use with Iphone 4S. Phone charges up when phone is placed in tray, press the Bluetooth Button in tray area for 3 seconds on key position 0 turn to key position 1 and release after 3 seconds, no lights illuminate on the unit as directed in the instructions.......... so my questions are
1. Is the Iphone 4s Compatible or do I need a specific ULF ?
2. Are the instructions on pairing correct?
3. do I actually have to have the phone in its clip in adaptor to pair or is that just a charging and antenna extending facility?
4. If there are any checks that I can do to make sure that A the head unit is operational on the Bluetooth side of things and B if the ULF is working as it should do?

Thanks for any help you could give me

Cheers

Rob
