What kind of problem are you having? Mine works just fine. Press the phone button say menu, pair a phone, set the code (1,2,3,4) then go to iphone settings, blue tooth, find uConnect type in (1,2,3,4) and there you have it.
Press menu button on 430N. Press Voice command botton on unit or steering wheel. Say "Main Menu" when prompted. Say "system setup". Say "Bluetooth device". Say "pair a device. Next follow the prompts, name your device, set the four digit code, then go to your iPhone settings, Bluetooth, and pair the phone to the Uconnect discovered by your iPhone. Set your phone up as priority one to seven, one being the highest. That should do it.
I set mine up, but find the 430N doesn't automatically connect to my phone most of the time. I have to go through the menu and command it to connect. Pain in the arse.
