When Android Auto stops working, the fix is almost always one of six things: the wrong USB port, Bluetooth or Wi-Fi switched off, a stale app cache, an old pairing clashing, a recent update, or a phone that needs a clean re-pair. This is a symptom-by-symptom guide written for South African drivers, and it is honest about which problems are your phone or car rather than a wireless adapter, so you fix the right thing the first time.
Running a wireless adapter and not sure it's the right one for your car? Check your make, model and year on the free SA checker. Otherwise work through the fixes below.
Start Here: The 60-Second Reset
Before changing any settings, fully restart both the car and your phone, because a clean restart clears most Android Auto connection problems on its own. Switch the car off completely, wait 30 seconds, and start the engine again. Restart your phone at the same time. Then give it a full minute to reconnect.
This works because the connection is a handshake between your phone, the car's head unit, and, if you run one, a wireless adapter. When any one of them gets stuck, restarting all of them resets the handshake. If that fixes it, you are done. If not, work down by symptom.
Symptom 1: Nothing Happens When You Plug In
If you plug in with a cable and Android Auto never loads, the USB port is the first thing to check, because many SA cars have two or three ports that look identical but only one carries data. The others charge only. Move to the port marked with a small phone or Android Auto icon, and use a proper data cable, not a charge-only one.
Flimsy charge-only cables are a common culprit here. Use the cable that came with your phone or a known data cable. If a different port plus a good cable gets Android Auto loading, you have found it.
Symptom 2: It Pairs on Bluetooth but Android Auto Won't Start
If your phone shows as connected on Bluetooth but Android Auto never launches, both Wi-Fi and Bluetooth need to be on, and that catches most people. Wireless Android Auto uses Bluetooth for the initial pairing and then Wi-Fi for the actual data link. Drivers often leave Wi-Fi off to save battery, which quietly blocks the connection.
Switch Wi-Fi on and leave it on. Do not manually join the car's Wi-Fi network from your phone settings; leave it available and let the car handle the pairing. The same logic applies to wireless Apple CarPlay on an iPhone, which uses the same Bluetooth-then-Wi-Fi handshake.

Symptom 3: It Worked Yesterday, Now It Doesn't
A connection that suddenly breaks after working fine usually traces back to a stale app cache or a recent update. Corrupted temporary files in the Android Auto app are one of the most common causes of a sudden failure, and phone updates occasionally reset connection settings.
Clear the cache first. On your phone, go to Settings, Apps, Android Auto, then Storage, and tap Clear Cache, then Clear Data. Reopen the Android Auto app and accept the terms again to set it up fresh. If an update is the cause, check the Google Play Store for an Android Auto update and apply any pending phone software update too.
Symptom 4: It Connects but Keeps Dropping Mid-Drive
Repeated drops during a drive are usually a Wi-Fi band or interference issue rather than a broken adapter or car. Older single-band wireless adapters struggle in busy signal environments, which describes most of Joburg and Cape Town traffic. A dual-band adapter on the 5GHz band holds the link far more steadily, which is one reason the North-Link uses dual-band Wi-Fi across 2.4GHz and 5GHz.
If you are on a single-band import that drops constantly, that is the hardware. If you are on a dual-band adapter and still dropping, re-pair the phone, keep it out of a closed metal console, and avoid thick metal phone cases that weaken the signal.
Symptom 5: One Phone Works, Another Doesn't
If Android Auto works on one phone but not another, the problem sits on the phone that fails, not the car or adapter. That is the clearest sign your hardware is fine. On the failing phone the usual culprits are Wi-Fi or Bluetooth switched off, an outdated Android Auto app, missing permissions, or Do Not Disturb blocking notifications.
On the failing phone, confirm Bluetooth and Wi-Fi are on, update the Android Auto app, and check Settings, Apps, Android Auto, Permissions so that Location, Notifications, Contacts and Phone are allowed. Then re-pair that phone. On an iPhone running CarPlay, the equivalent is confirming Siri, Bluetooth and Wi-Fi are on.
When It's Not the Adapter or the App at All
Some failures are the car's own Android Auto support, not anything you can fix on the phone, and it helps to know the difference before you buy or return anything. If your car never showed wired Android Auto in the first place, a wireless adapter cannot add it. Run the cable test: plug your phone in with a data cable, and if standard Android Auto or CarPlay does not load even wired, the issue is the car, not the adapter.
A small number of older Chinese-brand trims, more common on older BAIC than current ones, shipped with a proprietary system called Carbit Link instead of standard projection, and the cable test catches that case too. Most Haval, Chery, Omoda, GWM, Geely and BYD cars sold in SA today support standard Android Auto and Apple CarPlay and connect normally. For deeper car-side faults, Google's Android Auto compatibility and help pages and Apple's CarPlay help page are the right next stop.
A Note on Courier Scam Messages
Worth flagging for anyone buying car gadgets online in SA: ignore any post-checkout message asking for an extra courier fee, because it is a scam. Scammers send SMS or WhatsApp messages posing as the courier, asking for a small amount to release your parcel, with a link to a phishing page that steals card details. Northly settles courier costs at checkout and will never send a payment link afterward. Verify directly if anything looks off.
Frequently Asked Questions
Why is my Android Auto not working?
The most common causes are the wrong USB port or a charge-only cable, Wi-Fi or Bluetooth switched off, a stale Android Auto app cache, an old pairing clashing, or a recent update. Restart the car and phone first, then work through each symptom in order.
How do I reset Android Auto?
Go to Settings, Apps, Android Auto, then Storage, and tap Clear Cache and Clear Data. Reopen the app and accept the terms to set it up again. Forgetting the car under the Android Auto connected-cars settings and re-pairing clears most stubborn cases.
Why does my Android Auto connect on Bluetooth but not start?
Wireless Android Auto needs both Bluetooth and Wi-Fi switched on, because it pairs over Bluetooth and then moves the data link to Wi-Fi. Leaving Wi-Fi off, which many people do to save battery, blocks the connection from completing.
Why does Android Auto keep disconnecting while driving?
Repeated mid-drive drops are usually a Wi-Fi band or interference problem rather than a faulty device. A dual-band adapter on 5GHz holds the connection more steadily. Re-pair the phone, keep it out of a closed metal console, and avoid thick metal cases.
Could a wireless adapter be the problem?
It can be, but it is the least likely cause. First confirm wired Android Auto works in your car with the cable test, then rule out the phone-side issues. If a phone that works elsewhere still fails on a known-good car, contact Northly; the North-Link carries a locally honoured warranty.
Still not connecting after all of this? WhatsApp Theron with your car make, model and year and he'll help you pin down whether it's the phone, the car or the adapter.
The Short Version
Restart the car and phone first, then fix by symptom: use the data USB port and a real data cable, turn Wi-Fi on, clear the app cache, and re-pair after any update. If wired Android Auto never worked in your car, the issue is the car, not the adapter. If your adapter is an unstable single-band import, a dual-band North-Link is the steadier fix, with SA stock and local support.
Adapter dropping, or bought the wrong one?
The North-Link uses dual-band Wi-Fi for a stable wireless Android Auto and CarPlay connection, ships from SA with a locally honoured warranty, and comes with direct WhatsApp support if setup gives you trouble.
