I just finished building a car audio dock cable thanks to a few posts here on XDA. I have an I777 GalaxyS2 from AT&T. I want to run WiFi tether, BlueTooth, and GPS w/ Google Nav, and Auto-Brightness simultaneously and have the phone charge. Currently, I can't do it. The phone seems to be losing charge. Am I reading this thread correctly, and seeing that it isn't possible due to the draw of all those apps/functions? I have a 1A adapter in the car, so it should be getting enough power. Thanks!
