Man I am trying to figure out my Aha & App Radio applications as we speak for my AVIC-X940BT. The Aha i have working, but the AppRadio one is giving me fits. Can't get it to connect, or display anything. The one app I was working on is Dash Command. I'd like to do away with my Scan guage II and be able to see/control the engine parameters through the application.
I originally modded a dell streak 7 into mine, looked really clean but had some issues with battery life and volume controls and such so I bagged it, the appradio with arliberator has worked the best for me so far.
The guy who did his nexus 7 into the dash had similar issues too. I remember he dramatically altered it, he took the tablet apart and moved the power buttons and volume rockers and mounted it in like a pro. It was pretty neat. It just seems too time consuming to carry out to completion. haha
