iPad Project in Land Rover Discovery
I am posting here to discuss some technical details regarding an iPad installation in a 2004 Land Rover Discovery. I am replacing a long time tested MacMini installation that I have really enjoyed over the past years. Since the iPhone came out I have been waiting for this exact device to take its place. Turns out its 7.47" width will fit perfectly between the 7.5" dash trim that outline the 1 DIN opening on the Discovery. Using a fabricator friend of mine I already began designing/creating a very rugged mounting system that will be made from aluminum. The mount will actually be a full size 7x2 1 DIN box with an "arm" that will extend to securely hold the iPad. The mount will have a small amount of tilt adjustment but will have a cam that will allow it to rotate to landscape and lock in that position. I made a little rendered photo showing at the very least the proportions of the device on the dash. Anyway...on to the technical questions.
My question stems around connections...mainly audio and power. My disco essentially has no head, just an AMP. I have two left/right RCA type audio inputs (existing behind the 1 DIN area) with no ability for volume control. I always relied on the volume control of the MacMini to handle that but that is obviously not possible going through the 30 pin connector in a line out manner. I assume that I will be essentially plugging in an 3.5 mm audio jack splitting to RCA for iPad controlled volume and then a 30 pin connector for power. Knowing this I obviously want to minimize the look of these cables. Does anyone make 90 degree angle 30 pin connectors to USB and 3.5mm audio jacks that are low profile? Regarding the power, what would be the best way to essentially hard wire a 30 pin connector with just power? I was thinking of basically gutting a cigarette lighter charger and hard wiring it but there has to be a USB based charging system that I can just provide 12v DC to and use a standard 30pin connector to USB cable.
Again I am just asking for your knowledge...if possible try to avoid posting flames about how the iPad sucks as a CarPC and what not (found plenty of that in the other iPad threads) but please share your constructive comments and ideas. I am really excited about this project and I think its going to work perfectly.
