I'm not sure exactly what level of prep you actually need, but I think I just have the basic phone prep which does everything I want it to.
I think it's great that my phone connects immediately to the car so I can make/receive calls on the move, and it accesses all my contacts and call history which I can navigate through on the universal audio. It also lets you have multiple phones (up to 10 I think?) registered with the car so if for example you are sharing the car with your significant other then you can easily connect either phone depending who is using it. It's very useful for me as I have a UK and German phone so I can quickly switch between the 2 depending on where I am...
