Why does the OEM car radio switch off after a few minutes of operation?
An OEM radio that switches off after a few minutes is usually not failing at random. Most often the problem lies in the power supply, communication with the car, overheating or the unit’s internal power supply. The most important thing is to distinguish…
Does repairing an OEM radio, navigation unit or amplifier make sense in a few-year-old or a much older car?
Repairing a factory radio, navigation unit or amplifier often makes sense even after the warranty has ended, because these modules are closely tied to the car’s electronics. In practice, it is not just about music…
Is mail-in repair of OEM electronics a good solution for workshops and dealerships?
In a workshop or used car dealership, a fault with a radio, navigation unit or amplifier rarely ends with a simple "swap it and check". In new-generation cars these modules work together with the display, bus…
Does no sound in the car always mean a faulty car amplifier?

Is it worth buying a used car amplifier instead of repairing your own?
Buying a used amplifier should not be the first move when the sound disappears from the car or crackling appears. In many cars, the cause of the problem is the power supply, ground, wake-up wire, radio,…
Repair or replacement of an OEM car radio – which is more cost-effective?
An OEM radio today is not a simple player, but part of the car’s electronics that works with the display, amplifier and communication bus. That is why a radio fault may look like a sound problem,…
How does OEM radio main board repair differ from replacing the whole unit?
When an OEM radio stops working, you need to establish whether the fault is in the module itself or in the car’s wiring. That is the key practical difference, because replacing a working unit will not solve a power supply problem,…
How coding and unlocking of factory audio equipment works?
A factory radio, amplifier or radio-navigation unit can stop working after the battery has been disconnected, a module has been replaced or after a series of failed code entry attempts. In such cases, the problem may not be only the…
Can disconnecting the battery cause problems with the car radio?
Disconnecting the battery can cause the radio, navigation or amplifier not to start up the same way as before once reconnected. Most often the problem concerns loss of standby power, entering protection mode…
