Hey Guys

Kind of new to the forum so I hope I started this thread in the right spot.
If you want to use your iPhone in your Discovery, check out replacement head units by OxygenAudio.com's "O'Car" or iRoconline.com.

I would highly recommend O'car as I have it: Just pull out your factory head unit and install it. The only thing is since Aple split the iTunes and Music app I am waiting for the update as when using the radio app, then launching iTunes app in the past, the radio would fade out and iTunes launches, but with iOS5 you need to turn "Off" the radio app. I would imagine they will fix this.

I use the iPhone 4 for controlling everything with the Radio and Sound app that are free to download, to running iTunes and all the phone features via Bluetooth (O'car comes with Bluetooth mic), to my TomTom GPS app (great because the head unit is high up on the console). Just get the little trim bezel since the factory radio is a little larger than a sinlge-din size replacement head.
