Snap in adapter 84 10 9 182 792 is for the 1G iPhone. The 3G adapters that I have been receiving from Bimmernav for mods are 84 21 2 151 038. Have not seen the 3G iPhone adapter 84 21 2 151 043 so cannot comment. Suggest contacting Bimmernav to see if they have any information on this part. The other 2 iPhone adapters require modification to fit into the console eject box and the console eject box also requires modification.

Only comment I have on the external antenna is that unless you are on the fringe of cell coverage ( I am ) not that big of a bang for buck. Not sure from your comments if you have BT in your X5 or are looking to install it, so as far as the bumper antenna, no experience in installing one in an e53. Perhaps someone here or over on the BT forum on bimmerbaord can help you out.

Hope this sorts some of the confusion, not adds to it.
