Android Auto connection problems are often blamed on the phone, but the issue can also lie with a car's infotainment system, which may need its own firmware update to work properly. This matters because drivers troubleshooting dropped or failed connections may overlook the vehicle's software entirely, repeatedly checking cables and restarting their phone without addressing the actual cause on the car's side.

Google recommends restarting the infotainment system and, for aftermarket units such as Pioneer or Kenwood, checking the manufacturer's website for firmware updates. Automakers including Hyundai and Chevrolet have issued updates improving Android Auto reliability, such as Hyundai's February 2026 update for ccNC-equipped European cars, which sped up reconnections and added automatic restoration after a restart. Update methods vary by manufacturer, using Wi-Fi, USB drives, SD cards or dealer assistance, so drivers should consult their carmaker's website and provide VIN details where needed, or visit a dealer if the process is unclear. Firmware updates cannot add Android Auto support to incompatible hardware, and if problems began right after a phone update, Google's Known Issues page should be checked first, as it recently addressed connection bugs on Pixel 10 and Samsung S26 devices.
