Automotive Computing (R)Evolution - The Android Head Unit Build - Road Test!

Well, the first full week worth of road testing the ODROID-X2 is in the books. Overall I'm delighted with my windows car PC replacement. Key improvements over my previous install include the time from ignition to boot, access to all of my media needs via existing applications, and the system absolutely flies. I cant get over the speed of the ODROID-X2. Even comparing it to my collection of Android based tablets, it really does breeze through everything I want it to do. Whether navigating, watching YouTube, or playing an emulator, the system never misses a beat. Configuring the UltraCarHome application with all of my frequently used programs was also a snap. I've also managed to get some functionality out of the SpaceNavigator, allow me to access all button controls on screen and swipe between main menus in UltraCarHome. I'm sure that with more bench testing I'll unlock a greater set of functionality.
As with most test scenarios however, I do have a couple of complaints with the install as it stands. The Anker external battery pack is not living up to my expectations. It appears the battery life is heavily effected by the ambient temperatures. Inside, the battery lasts for several days under a charge with no power usage mitigation. In the summer heat inside the vehicle, the battery barely manages to last 10 hours. Also, at 1.5A input maximum, it takes close to a full day to charge the battery, meaning my car will never truly charge the battery properly. The Anker portion of the project will be scraped for now.
Another problem I am not so surprised with is touchscreen accuracy. The higher on the touchscreen I press, the more inaccurate the points become. It becomes burdensome in apps where the menu or other controls are on the top 75 pixels on the screen. I'll have to do more modifying of the kernel to attempt to correct this problem.
The final gripe I have at this point is one that many tablet owners have come to somewhat expect. Despite the fact that my area has 4G LTE coverage, there are points where I wish the ODROID-X2 wasn't so heavily dependent on a network connection. Because the X2 doesn't have an internal battery, it needs internet access to correct time/date settings after a cold boot. Also, at times it takes upwards of 30 seconds for the X2 to scan and pick up my mobile hotspot connection. There have not been times where I've been left with buffering messages on the go, but I find myself waiting for that internet icon to display before I really feel like I can enjoy my X2.
These small issues aside, I definitely still get excited when I can start my car and not see resume problems, BSODs, or configuration issues. The ODROID-X2 already feels closely integrated into the vehicle, and I'm definitely ready for more bench testing to continue to maximize its potential.

thats pretty radical and way better than the big ### screen inside a tesla have you seen those things they are radical but annoying i would think.Very interesting install, seems like an application such as this would come in very handy. However, it occurs to me that the bezel from your Lilliput is getting in the way especially when needing to interact with the edges of the screen, I would suggest using a multi-touch capacitive glass overlay, eliminating the bezel all together, the Occular panels I use in my installs would work very nicely. Great job by the way.Any updates on this build. I have google Glass and want to build something like this, so that I can interact with it through glass and voice actions.
