Right, but I don't want a fully featured Car Home app since I just use Google Music or Navigation while driving - I really just don't need all the bells and whistles, I just want the physical interaction of plugging in the device to automatically set the phone into a docked mode that keeps the screen on, or in other words, car mode that does that inherently. It worked just fine in the past, but since 4.1.2, this whole docking situation has been screwed with unnecessarily by Google! Hmmm... I just thought of something.... brb to test just having Tasker start that Car Mode Control app and nothing else! May have figured it out here!

EDIT - IT WORKS! Okay, shouldn't be this excited, but it's nearly 2:30AM, and once again, I've spent too much time working on something related to my phone.... so here's what I've got going on, and even though I kind of hate having to jump through this many hoops to get it working the way it was before, there's an added "benefit" of doing it this way, and here's why it's in quotes:

WHAT THIS DOES - Sets the iBolt xProDock "docking mode" into "car mode," which is two different things. Docking mode does not keep the screen on while docked, which is a problem if you use your phone to access apps like Google Music and Navigation while driving (note how I wasn't talking about texting and driving for a reason!), but it does give you a cool menu bar on your pull down notification menu of recently used apps while docked, can be kind of useful if you regularly only use a few select apps while docked. Car mode keeps the screen on, but since the iBolt dock and everything else after 4.1.2 won't recognize a dock mount instantly turning on car mode, this is how you can trick it into doing so and also retain the dock mode notification menu apps list!

STEP ONE - Download Tasker or A2DP Volume (the latter is free to use in case you didn't want to pay for Tasker) and also Car Mode Control

STEP TWO - Use Tasker or A2DP Volume to manipulate the Home Dock (what iBolt is using to go into docking mode) to automatically launch Car Mode Control. How to do this depends on the app, but it's pretty simple for either one.

With Tasker, start a profile for State > Docked > Type > Desk. For the Task you'll need to perform, I first have Keyguard set to Off to turn on the screen and unlock the device, then Load App > Car Mode Control. For the Exit Task, I kill everything - Car Mode first, Music, Navigation, Maps, all with "Use Root > On" selected for some extra power to do what I want it to do. Then I have it set to turn Keyguard back On, but that doesn't hardly work for some reason. You'll want to either create another profile for State > Docked > Type > Car or use A2DP below, at the point where I have an asterisk. If you're wondering why I didn't use State > Docked > Type > Any, it's because you want the Desk dock to launch the Car dock - doing Any will just confuse Tasker for a second or two and load the Desk dock and then the Car dock, and THEN the Car dock again since you're setting it to effectively start the Car Mode Control app.

With A2DP Volume, a handy app you should have anyways regardless of whether or not you use A2DP streaming through Bluetooth, create a profile for Home Dock first, and have it ONLY Start app on connect > Car Mode Control. Then go back one, and edit the * Car Mode profile, and this is where you have it launch just one app of your choosing, mine being Google Music. You can also check Stop app on disconnect, and anything else you might find useful - like setting media volume, etc.

With either path you chose, using Tasker AND / OR A2DP Volume, you should have two icons on your notification bar, one for the Dock Mode and the other for Car Mode.... When you pull down your notification bar, you'll see the list of recent apps for Dock Mode, and an ongoing notification to click and turn off Car Mode (unfortunately, that's kind of stupid, but oh well, it's always been like that). And the best part, the point of this whole post...... the screen WILL stay on while docked!

Hope this helped someone other than just myself, man, it's quite the headache and I've got apps pointing at other apps all over the place for no damn reason, but this certainly does the job!
