## Review summary

OBD Fusion is praised for a strong, professional feature set and Android Auto support, and for not requiring a subscription. However, multiple reviews highlight reliability issues (disconnections, zero readings) and Android Auto connection problems. The pay model for enhanced PIDs and annual licenses, plus refund difficulties, is a frequent gripe. Some users also report missing PIDs or dashboards for certain vehicles. Overall, it’s a powerful tool when it stays connected, but reliability and pricing are the main concerns.

### Pros

- Powerful, professional-grade feature set with many enhanced PIDs and modular add-ons.
- Android Auto compatibility lets PIDs be displayed on the car screen while driving.
- Not subscription-based, avoiding ongoing recurring fees.
- Ease of use and ability to customize the UI and dashboards.

### Cons

- Unreliable connectivity: frequent disconnects and readings showing as 0s when it should be live.
- Android Auto may not auto-connect and sometimes requires manual reconnection when starting the car.
- Paywall/fees for enhanced features and yearly licenses; refunds can be difficult or slow.
- Incomplete PID coverage and dashboards for some vehicles (missing critical PIDs, dashboards, or modules for certain makes/models).
