Just finished my weekend DIY. Wanted to get some "Extra features" on my 430N. Purchased a mygig unit a few months ago, and upgraded to the new Iphone 5. (Damn Lightning cable). Wanted to share the install and show some picts. Very happy, i'm able to watch videos Netflix etc while waiting in the car.
Installed Converter behind the Glove Box
Purchased a HDMI To RCA Convertor
(Make sure you add the USB Power to the unit otherwise it won't work)
Fished a HDMI Cable under the carpet, to the glove box. (easy access to iphone.)
Had to purchase the Iphone to HDMI Converter.
All in all took me about 2 hours to finish the install. Hardest part was to get the power for the HDMI Converter, and get the cables behind the unit to plug in. Hope that helps someone.
