I am having an awful time taking my iPad and iPhone with me in our vehicle. Often the iPad is in a bag in the cargo area and my iPhone is in the front seat. Then, always while driving, I learn the iPad was linked and my phone was not. Is there any way to stop this besides turning off Bluetooth on my iPad? The problem is I never remember to do it. But I can't make a phone call or use anything when it links with my iPad! And it takes a little bit before I remember the iPad likely linked. When I fuss with the controls it eventually tells me. At this point, I am usually on the road and fixing it requires I park the car, go to the rear end and get the iPad out to fix it. It's very annoying. Suggestions, please.
