Hardware issues, though less common, are also part of the equation. The small antenna adapter that connects the car’s OEM antenna to the MTCD unit’s ISO connector is often poorly shielded or incorrectly wired. If the radio app shows signal strength but produces only hiss, the problem may be a missing 12V power feed to the antenna amplifier. Similarly, a loose ribbon cable between the main board and the radio module board inside the unit can cause intermittent failures. Making the app work, therefore, sometimes requires physical inspection: reseating cables, verifying antenna continuity, or even replacing the internal radio module itself.
