Iphone 4 wont discover bluetooth devices ie. my car
Out of the blue my iphone 4 has stopped connecting with bluetooth devices. I removed my car builtin bluetooth out of my phone and took my phone out of the car's system. It was synced to the car's system but just stopped working. Car is brand new 2013 Ford Explorer & I'm sure it's not the car. I've tried to add the phone but it just spins and says discoverable but does nothing. This is why I'm sure it's the phone! It won't discover any bluetooth device. I have shut off my phone, reset my phone, made sure my phone was charged, deleted things that could be taking up to much memory etc. My phone software is current @ iOS 6.1.3
Please help!!!!
iPhone 4, iOS 6.1.3
