  • Hum Equipment
Can Hum unlock or start my car?
No, Hum cannot unlock or start your car.

Can I plug my Hum OBD (On-Board Diagnostics) Reader into an extension cable or an adapter?

Using an extension cable or adapter with Hum will void your equipment warranty. Doing so may interfere with Crash Detection functionality as well as communications between the Hum OBD Reader and your vehicle.

Can I use Hum if I don't have a smartphone?

Absolutely! You can keep track of your Hum account using the Hum Customer Portal at customer.hum.com. You can also use the Hum App on your Apple or Android tablet.

Hum App
In order to use the free Hum App, you must have an iPhone running iOS 8.0 or later or an Android smartphone running Android 4.1 or higher.

Can I unplug the Hum OBD (On-Board Diagnostics) Reader while my car is on?

No. You need to turn your car off before unplugging or plugging in the Hum OBD Reader.

Does Hum drain my car battery when the engine is off?

When your car is off, the Hum OBD (On-Board Diagnostics) Reader goes into a low power mode.

If my Hum Speaker is turned off, will Hum still work?

The Hum Speaker's on-off switch only controls the hands-free Bluetooth® function. Calls to and from Hum Customer Service and Hum Emergency Response will go through as long as the Hum OBD (On-Board Diagnostics) Reader is powered and within cellular coverage (even if the hands-free switch is off). Many Hum features—Auto Health, Driving History, Boundary Alerts and Vehicle Location—do not involve the Hum Speaker at all.

How will I know if the Hum OBD (On-Board Diagnostics) Reader has come unplugged?

If you think your Hum OBD Reader has come unplugged, you can check the Hum App or portal to see if your driving history data has been recorded. If you forget, Hum will automatically notify you if your Hum OBD Reader has been unplugged for 10 days. You'll then receive an email when you've successfully plugged it back in.
