1st Post. (Cross Post from Audi B7). Hello All. I searched a bit, and didn't find a specific answer. Maybe you guys could help.

I just got this head unit as a gift from my Fiancee for the holidays (I know shes amazing) and I am trying to figure out exactly which items I need to install it? Preferably at the best price available.

A few things that I am hoping to accomplish:

1) I want to connect my existing steering controls to the head unit. I found 3 items that claim they do this. I am not sure which one is best, can I go with the cheapest and still get the same effect? Will these allow me to press the button for Bluetooth as well? 2) I want to be able to use my iPhone 5, as well as charge it. Is the Pioneer CD-IU50V a must? Can I just hook up a regular iPhone USB cable into the USB slot to accomplish this? I saw that you can wirelessly send info from the phone to the head unit. If this is the case I will just get a standard charger and be done with it. Unless one method is better than another I suppose.

3) Traffic would be nice but not a must. I heard that the Aha Radio iPhone app helps integrate updated traffic, but I also read that I need an adapter. Anyone know for sure?

I will be getting the Connects2 CT23AU01A Dash kit, which based on the videos I saw looks the cleanest installed, unless someone can recommend a better one.

I was told by the Sonic Electronix website that I also need an Antenna adapter - Scosche VWA-4B and a standard harness - Scosche VW03B / VW03

Am I missing anything? I would like to order everything by the end of the weekend. I'd hate to wait an additional week after I take everything apart and realize I am missing something.
