Hello. I am looking for an app that will keep the A2DP Bluetooth profile constantly turned on. I am trying to stream Google Navigation voice directions from my Optimus S 2.2 Froyo non-rooted phone to the receiver in my truck. The connection works, but I lose the first second of the voice prompts because Android disables the A2DP connection when not in use to save battery power. For example, If the voice prompt is supposed to say "turn right onto Main St", I will hear "onto main Street." I want an app that will prevent the power saving feature; something like a Wake Lock app perhaps? Is there an app out there that does this? Thanks!
