Phone not connecting, f11 5 series iPhone 5s

Hi I am completely stuck as to why my system wont work.



I purchased a 2010 (october) 520d Touring M Sport last month.



I purchased an iphone 5 snap in adapter (the media one)



but I cannot get the adapter to do anything more than just charge the phone?



I appear to be running:



TX-003.004.031 Software in the car and it will not let me update it beyond this.



I have a USB socket in the glove box which I tried connecting the iphone to via USB using its lightning cable (it is an iphone 5s) but the car doesnt even recognise it. The bluetooth and bluetooth audio appears to work but the car doesn't seem to think that the iphone exists. I have all my music on it.



The car has professional navigation but I am unsure as to what media system it has onboard. It does have the simple basic stereo 6 speaker system.



The BMW site lists the latest version as being:



TX-003.005.006-003.004 (which is 3 versions newer than mine) but it wont let me update to it using the cars data connection.



Any ideas? Is there anyway I can get the car to control the iphone? Other than just via bluetooh audio skipping track. Is there some kind of adapter I should be using to connect my phone or will this phone never connect via USB?
