Buy a Bluetooth OBD2 (ELM327) adapter. They cost about $10 – $25. But better to get a mini one to get it seated firmly into the OBD port.
Download free Troque app on your Android phone or tablet. The app is FREE to download and try.
Plug the OBD2 Bluetooth adapter into your car. The port is located under the dash, a little to the left of the pedals.
Open app and tap on “CUSTOMIZE”. It should automatically find your OBD2 Bluetooth device and connect to it, without you needing to do anything. If the device requires a PIN, you’ll get a pop-up asking for that. Try 0000/1234 if you don’t know it – that seems to be the PIN that most devices use.
When app is done reading settings from your car, it will show you the available customization categories. Pick “Instruments / Display / Dings”.
Tap on “Reverse-gear beep”
Change it to “BEEP ONCE” and press “SAVE”
If this is the first time you’re saving a setting with Torque app, it will guide you through the purchase process. The ability to change customization values (such as the beep) is a paid feature and costs $10
for unlimited lifetime use. You don’t have to pay again the next time you want to change a setting, even if it’s a different one, or even if you’re on a different phone (logged in with the same Google account).
Enjoy beep-free reversing!
