8. Řešení problémů
If you encounter issues with your PAC CH1A-RSX adapter, refer to the following common problems and solutions:
| Problém | Možná příčina | Řešení |
|---|---|---|
| Autorádio z druhovýroby se nezapne. | Incorrect wiring for 12V constant or accessory power; blown fuse; faulty PAC module. | Verify all power and ground connections. Check vehicle and radio fuses. Ensure the PAC module is receiving power from the vehicle harness. If the yellow wire (constant 12V) is hot but the accessory wire to the radio is not, the module may be faulty or not properly initialized. |
| Steering wheel controls do not function. | Incorrect SWC wiring; aftermarket radio not configured for SWC; incompatible radio. | Ensure the SWC wire from the PAC harness is correctly connected to the aftermarket radio's SWC input. Consult your radio's manual for SWC programming/learning procedures. Confirm your radio supports external SWC interfaces. |
| Navigation outputs (reverse, parking brake, illumination) are not working. | Incorrect wiring to navigation unit; navigation unit not configured. | Verify connections from the PAC module's output wires to the navigation unit's corresponding inputs. Check the navigation unit's settings for proper input recognition. |
| Adapter does not fit or connect to vehicle wiring. | Incorrect adapter model for vehicle; vehicle has a non-standard factory system (e.g., premium audio). | Double-check the vehicle compatibility list (Section 4) against your specific vehicle year, make, model, and factory options. Some premium sound systems may require different adapters. |
If problems persist after following these steps, contact PAC technical support or consult a certified car audio installer.
