I took back my car to address/add a few things to my setup:
1) As I was getting video distortion on both the factory screen and headrest monitors, I purchased a Pyle Video Amplifier and had it installed
2) I wanted a more seamless integration of playing music/videos through the iPhone/iPod. So I: a. Purchased a Pro-Clip mount specific for the M and iPhone holster, b. Purchased an A/V cable by i.Sound that works with the latest 3.0 firmware for the iPhone, c. Had two RCA jacks installed inside the armrest, where the top one taps into the factory AUX jacks, so I don't need to have wires exposed and hooked up to the back of the armrest, and where the bottom jack taps into A/V input 2 on the headrest monitor control box. This allows me to play the factory DVD on one input into the headrest monitors and the iPhone onto a second input to the headrest monitors, so the two headrests can have two different video sources.
3) I added 3000k yellow fog HIDs which I'll share some pics in a separate thread
Here are some pics:
The RCA jacks, the video amp, the HID Kit, and a 12 Volt jack I decided not to put in and decided to just hard-wire the power from the iPhone.
The Pro-Clip mount and holster, and my wife's old 2G iPhone (which has now become my kids dedicated iPod Touch with no phone service)
The iPhone mounted and my Blackberry Storm (for those with a storm, Arkon makes a great dash mounted holster, had to get it since in NJ it's illegal to use the windshield suction cup).
The Pyle Video Amp added. It was around $20. The installer at Installations-Unlimited.com applied the amp only to the additional signal line he pulled for the rear monitors and left the factory line as is. This solved the video distortion problem on all three screens.
The two RCA jacks installed in the center armrest. The top is tapped into the factory AUX, and the bottom is tapped to AV2 of the Headrest Monitor control box. This allows two video sources for the headrest monitors. (Eventually I'd like to install Flo TV, http://www.flotv.com
, Sirius Mobile TV, or an HDTV mobile tuner.)
The great thing about the i.Sound Cable Works iPhone A/V cable purchased here:
is that it also works with any other mobile device. Reason being, both the USB power and the A/V cable are plugged into a main iPhone style plug. So I'm able to remove the A/V plug and connect it to my Blackberry Storm, and I can play MP3s in my phone as well as use the iPhone.
iPhone connected to the i.Sound cable (pretty neat blue LED comes on)
You can clearly see two sources, one from the Factory DVD and one from the iPhone:
Another pic showing two sources.
The Pro-Clip in case someone wants to know what it looks like. With this mount, and plus I need the video capability as well, it didn't make sense for me to get one of those integrated kits from Peripheral/PAC as none of those kits do video as of now:
The Arkon mount for the Blackberry Storm in case anyone is interested:
All in all, a pretty clean install like I wanted. Other than the bit of wire near the Pro-Clip mount, everything else is pretty much hidden. I can easy access the iPhone screen with the mount and play music/videos as needed.
