[quote="bellnier"]You didn't ask about connecting mp3 players, but I'll throw in my 2 cents. I've got my iPod connected through second aux adapter on my HU (which the Pioneer AVH-P6800DVD does NOT have; you need to buy an adapter) with cable running out from under center console. This allows iPod control thru iPod only, not HU (which is my preference considering all the negative comments about many, many iPod controllers).

the AVH-P6800DVD does have a AUX in on it. there is a headphone jack (3.5mm) on the back of the radio so you can bring in audio from a MP3 player or iPod. you still have to control the iPod from the iPod. if you get the Pioneer iPod adapter then all your controls are on the radio itself. it's nice and easy to use.
The Sirius display is alright. It would be nice if all the info showed up at once in one spot instead of pressing a button to change the info. but I still like it.

BTW the AVH-P6800DVD is a really nice piece. I love it more and more every day.
