Radio wiring diagrams please?

When attempting to install an aftermarket head unit or a head unit from a different vehicle, compatibility issues may arise, especially with the audio system. Differences in wiring, connectors, and communication protocols can lead to sound issues or other malfunctions.

Here are some general recommendations when attempting a head unit upgrade:

Check Compatibility: Confirm whether the new head unit is compatible with your 2022 Kia Sportage LX in terms of wiring, connectors, and communication protocols. Some head units are designed specifically for certain models and may not work properly in other vehicles.

CAN Bus Connection: If the new head unit has a plug for the CAN (Controller Area Network) bus, it's essential to ensure that it's correctly connected. The CAN bus is a communication network in modern vehicles that allows various electronic control units to communicate with each other.

Audio Amplifier Compatibility: Some vehicles, including the Kia Sportage, may have a factory-installed amplifier for the audio system. When changing the head unit, it's important to ensure that the new unit is compatible with the existing amplifier or to replace it with an appropriate one if necessary.
