OK I've found a thread on this forum that I actually may be able to contribute too
!!!!!!!!
First off let me start by saying that I DO NOT have an iPhone yet. I'm only using my 5th gen 30GB iPod as a reference. I'm very big into modding cars so I have quite a bit of personal experience......
Here's the deal, any of you have an aftermarket radio DO NOT PAY SOMEONE TO DO THIS FOR YOU!!!!!!! Take this opportunity to learn something about your car and get that satisfaction of saying "Yep I did that myself!"
First thing to do is get a set of RCA jacks. Personally I have the
Apple AV Cable. The reason I have those is because I have a flip up screen in the Jensen head unit I have.....so YES those will allow video (again I'm not sure if the iPhone have a 'TV Out' function like a regular iPod does...I would assume so???)
Second.....if you don't know how to take your head-unit out search for a forum for the particular vehicle you drive. On those forums I would imagine there should already be a thread about how to take a head-unit out. The reason I say to find a thread about this is because SOMETIMES the entire dash has to be taken out. It's not near as hard as it sounds. If you find a good forum with people that make good How-To's there will even be pics that show you exactly where all the screws are
.
Once you have your head-unit out plug the cable into the Audio In jacks and run the cable from the back of the unit out the back and up to where ever you plan on putting the iPhone during driving. My car has a cup holder right between the 2 seats so I have my cable ran there
.
BEFORE you put everything back together make sure it works
. Once that's done put everything back together. THAT'S IT!!!!!!
In my SRT-4 it took all of about 5 or 10 minutes for me to do this. I didn't have to take the dash apart so it was just popping my head-unit out and running the cable.
