6. Кыйынчылыктарды
Орнотуу учурунда же андан кийин көйгөйлөргө туш болсоңуз, төмөнкү жалпы көйгөйлөрдү чечүү кадамдарын карап көрүңүз:
- Радиого кубат жок: Double-check the B+ (constant power) and ACC (accessory power) connections. Ensure the vehicle's fuse for the radio is intact.
- Динамиктерден үн жок: Verify all speaker wire connections (FL+, FL-, FR+, FR-, RL+, RL-, RR+, RR-). Ensure the aftermarket radio's amplifier is enabled and functioning. If your vehicle has a factory ampкөтөргүч, камсыз кылуу amplifier turn-on wire from the new radio is correctly connected to the harness's amplifier remote wire (if present).
- Рулдун башкаруу элементтери иштебейт: Confirm that KEY-1 and KEY-2 wires are correctly connected to your aftermarket radio's SWC inputs. Some aftermarket radios require programming or learning of the steering wheel controls. Consult your aftermarket radio's manual for specific instructions. Ensure no SWC wires are inadvertently grounded or connected to other live wires.
- No Bass or Poor Audio Quality: This can sometimes indicate an issue with the amplifier turn-on signal if your vehicle has a factory ampөмүрлүү. Камсыз кылуу AMP-ON wire is correctly connected and receiving power when the radio is on.
- Арткы камера иштетилбей жатат: Check the connection of the 'BACK' wire (pin 03) to your vehicle's reverse light signal or the reverse trigger wire from your camera. Also, ensure the camera's video signal is correctly connected to the radio.
- Radio Reception Issues: Ensure the antenna adapter is securely connected to both the vehicle's antenna and the aftermarket radio. Verify the ANT.POWER wire (pin 13) is providing power to an amplified antenna if your vehicle requires it.
