2004 vs 2005 Bluetooth w/ iPhone

[BimmerDC]

I know this topic has prob been beaten to death so forgive me for starting a new one. I've read through a lot of threads and just want to make sure I've got everything..

1. Late model 2004's have the bluetooth option
2. There is a different bluetooth in each year... Visteon module 2004 and Motorola module in the 2005

I am looking at a 2004 3.0i sport/prem pkg prod date 8/05.. First I want to know what the odds are that it has bluetooth.. second, if my iPhone will work with the Visteon module..

Thanks for your help
