Buying Tips & Best Practices
Before purchase, confirm that your vehicle’s make/year is supported for advanced functions.
Always update the app and firmware to the latest version for maximum coverage.
When unlocking extra vehicle software, do so gradually as needed rather than all at once to manage cost.
Keep the device firmware, app, and vehicle software versions in sync to avoid compatibility issues.
Use in a good environment: stable power (9–26 V), avoid extreme temperatures during operation.
Back up and record codes before clearing so you have a diagnostic trail.
