You know that the new Android powered HTC Droid Incredible comes with a TV-output capability right. Now, that is something that you could use to connect your Droid Incredible to the in-dash GPS screen on your car. At least that is something that this gentleman has done and the output, as you can see from the video is truly amazing.
The display rendered on the GPS screen retains the orientation of the Droid Incredible and is affected by the accelerometer movements as well. While that is an interesting sidenote, an important point to note is that the controls have to be still navigated only through the phone’s touchscreen. That makes it difficult to use while you are driving.
Nevertheless, if you are looking to add some spice to your mundane travels, this is something that you could try out.
