I really want an aux input jack in my car so that I can plug in mp3 players (with a standard 3.5mm headphone cable).

As far as I can tell, I want the Blitzsafe AUX DMX V.1B Auxiliary Input Adapter (as per http://www.discountcarstereo.com/detail.aspx?ID=1170).

My car is a 2005 A4 B7 with the bose sound system. I have the in-dash 6-cd changer, and don't have a second CD changer. I don't have the navigation package, but my car does have satellite radio. I just want to make sure that the adaptor works for my car without needing to remove satellite radio before I buy one.

My car stereo looks like this:


If the adaptor works, it's just a simple matter of installing it and finding a component audio to 3.5mm cable. (I found a walkthrough on another forum).

The whole thing is a very simple process, I'm just not sure if that Blitzsafe adaptor will work for my car (and if that's the cheapest place to buy one; does anyone know somewhere less pricey?)

Any input would be much appreciated.
