I have a Pioneer DVD head unit in my car that can use bluetooth for in car speaker phone though the iphone. Instead of having to toggle it on and off when i get into the car is there an app that will switch on the bluetooth when charging?
Thia would save a lot of battery life as i wouldnt have to have bluetooth on all of the time nor would i have to switch it on everytime i get in and out of my car.
I want to know the same thing. I have a bluetooth device in my car that I never use it because I keep bluetooth off to save battery, but I do charge my phone while I drive.
