Awesome job. I have seen this done with a nexus 7. I beleive he is using bluetooth to the stock head unit. so his controls on his steering wheel should still be working.
What head unit did you have to begin with? Just wondering why they didn't use the stock head unit? I am guessing the aftermarket head unit is of higher quality...Several of these have already been completed, this has been the first one on a Super Duty. The steering wheels controls work As if the factory system was in use. Has Bluetooth phone capabilities like the factory sync system. The radio app allows control over all the radio sources and volume control. Where this setup shines is with the uses of all the other Apps available for the iPad. Ex. Maps, weather, pandora, and all the many others.
