I have just purchased my first audi and it is amazing.
I have the A4 quattro v6 3.0 with the bose system in dash cd changer and intergrated satellite radio. It is a sports package so the steering wheel doesnt have integrated audio controls.

I have seen several options for aux units that plug into the external cd changer spot. one at best buy, several densions (but a big pricey) and icarkit

my question is what have people used, any installation tips or tricks?

the product would need to fit an iphone 4, charge and take calls. bluetooth would also be a nice feature.

thank you ahead of time

 

I have been shopping around for this as well, they are pricey. Most all that I have seen plug in where you sat radio does, so you lose the sat. I love my xm, so dont wanna do that. Havent found one yet that can, so I think I will be waitng untill I can just change out headunit to screen with nav, bluetooth, xm, and ipod. $800 ++ If the sat radio isnt an issue for you look at denison icelink, or Dice. You can sometimes find used ones on here and other forums for good deals, you just have to stay on it. They go fast. If you want ipod and bluetooth, its gonna get pricey. Crutchfield has a Kenwood thing that hooks up, and can have ipod, bluetooth, sat, etc for less than $100 but has a small screen, and I couldnt find where to put that and im sure price goes up as you add options. Worth looking into though.
