Step One: Check the Cable and Bluetooth ConnectionsThis may seem like a no-brainer, but if you’re using a dedicated Auto head unit, the cable is the first place to start. If Auto simply isn’t loading for you, try swapping out the cable for a different one. There’s a good chance the one you’re using has been damaged, which can cause all sorts of weird issues.Along those same lines, make sure your phone is paired and connected to your car’s head unit. While Auto does most things over USB—play music, Maps voice commands, etc.—it does rely on Bluetooth for voice calls. You’ll know if you have an issue here pretty quickly—just tap the phone button in Auto’s menu. If it tells you to connect your phone to make calls, then Bluetooth is disconnected.
Aug 03, 2009 Just because it's not what you or I would do, doesn't make it the wrong thing to do. Yesterday I installed a new head unit, four speakers and a 4-channel amp into a Ford Explorer. The factory system included an 8-inch sub. I integrated it by soldering an RCA cable onto the factory signal wires and plugging it into the new head unit's sub output.

You’ll likely need to unplug the phone from USB and return to your head unit’s settings menu to re-pair the device. For exact pairing instructions, consult your car or head unit’s instruction manual. Step Two: Check the App’s Permissions and Notification AccessFrom this point forward, the rest of our suggestions will apply to both the native phone Auto interface and the head unit. So if you’re having issues on either interface, try these.RELATED:App permissions can cause all sorts of weird issues if they’re not enabled, or have somehow become disabled.
So if you’re having issues with phone calls, notifications, voice controls, or any mix of the bunch, this is where I’d start.NOTE: the following steps were done on stock Android, so they may be slightly different depending on your handset’s manufacturer.To check permissions, jump into Android’s settings menu. Pull down the notification shade and tap the gear icon.From there, scroll down to “Apps.” It may be called “Applications” depending on your phone.Tap “Android Auto,” then “Permissions.”. From here, just make sure everything is enabled.
