I have a car dock and when I Dock it the default car mode screen comes up and I LOATH it. IT is not google maps, it is the Verizon navigator. I am now using Car Home Ultra - https://market.android.com/details?id=spinninghead.carhome, it is a great replacement. What I want to be able to do is, change what comes up when I dock the phone. Is there an app that changes default apps for certain activity's. For example, I want Car Home Ultra to launch when I dock my phone in the car.
