I use HTC Legend with Copilot Live 8 as a GPS on motorcycle rides. I put the Legend in my pocket, plug in a pair of headphones and use the audio instructions to get to my destination. Now, the problem is that when I turn the screen completely off, Copilot audio turns off as well. The program itself continues running and tracking my progress, but I don't get audio turn-by-turn instructions. So Copilot works fine but having the screen on in my pocket drains the battery for no reason. I don't know if this is a limitation of Copilot or Android or Legend - but is there a way to turn off the screen while I still get audio to save battery? Also, is there an easy solution to run audio from an iPod to the same set of wired headphones while getting GPS guide from Legend? Is a cheap splitter cable the easiest solution?
