Google’s Android Auto Will Now Tell You If Your USB Cable Is Bad

The latest Android Auto update adds a diagnostics feature that checks to see if your cable or USB port isn’t working as expected, as reported by the old XDA Developers editor-in-chief Mishaal Rahman on Twitter. If your phone is not connecting to your car, the diagnostic tool may be able to determine if the USB connection is where the problem lies.

In the images shown by Rahman, the tool, apparently called “USB Boot Diagnostics”, will check if a USB cable connects and checks the quality of the cable. On a support page, Google recommends using the connection to your car with the cable that came with your phone or a cable less than three feet long and does not use USB hubs or cable extensions.

Having the right cable might be easier said than done, however. USB cables can vary widely in quality, which means it can be difficult to know which ones have the right specs to support Android Auto. And you also might not be able to assume that the cable that came with your phone will work with Android Auto, since most newer phones come with USB-C cables, but few cars have USB-C ports. Hopefully this diagnostic tool will make it easier for you to know if you need to get a different cable.

Rahman says the tool is available in Android Auto 7.5.121104 – if you don’t have that version yet, you might want to check if you have an update available. It’s worth noting that Google sometimes rolls out features slowly, so if you don’t see the diagnostic tool, you might have to wait for it to become available.
