If your phone hasn't got remote sim it won't work with the factory kit,
When you turn the ignition on the rcd asks for your phone pin no, after that is entered it connects and copies your sim card into the RCD memory and imobilises your phone (cannot use your phone at all) all calls etc are done through the mfsw or the rcd, a bit of a pain but when your use to it the kit works very well.
Hope this helps 
sorry mate but whats a remote sim?
look through your phone and activate remote sim card, where something else can read your simcard via bluetooth,
My phone kit wouldn't work when i picked my car up and dealer said that my phone wasn't compatable with the kit

i looked through my phone manual and saw that remote sim card mode in the phone had to be turned on, and just enter security pin no that you use when you turn the phone on, now works a treat
(i have got a Nokia N86 8Gb)
