Mail-in repairs, available throughout Poland
Tomasz Mazurkiewicz is the founder and owner of the OEMatic brand – a workshop specialising in repairs of factory-fitted car radios, navigation systems and amplifiers. For over 15 years he has worked with OEM electronics, combining day-to-day workshop work in Sochaczew with postal servicing for customers across Poland. His published texts are based on real jobs – from identifying faults in audio modules and displays, through CAN bus diagnostics, to restoring security codes and soldering SMD components. He writes the way he speaks to customers: clearly and with an emphasis on what really works. Every article on oematic.pl is based on his own experience gained with factory car electronics.
The difference between an OEM and an aftermarket radio is seen mainly in how it works with the car, not just the logo on the panel. That determines whether the fault can be eliminated…
When repairing a factory radio, amplifier or navigation unit, the most important thing is to identify the real cause of the symptom, not to swap parts quickly. No sound, a screen restart or a non-working GPS often result from...
Repairing an OEM factory radio, navigation unit or amplifier usually does not require bringing the whole car to the workshop. In many cases, removing the module itself and sending it for bench diagnosis is enough.…

The warranty after OEM electronics repair is not a general promise for the whole unit, but a description of the service department’s specific scope of responsibility. In practice, it is determined by what has been diagnosed, repaired…
Repairing a radio, navigation unit or amplifier usually starts with gathering a few details that matter technically to the workshop. The symptom alone is rarely enough, because no sound or a lockout message…
In repairing a radio, navigation system or amplifier, the hardest part is not the soldering itself, but correctly determining what has actually failed. The same symptoms can be caused by a lack of power in the car, damage…
Once the unit reaches the workshop, nothing happens by chance. First, it has to be established whether the problem concerns the electronics themselves, memory, a lockout, or communication with the car. This first stage often…
Before sending off a radio, navigation unit or amplifier, it is best to prepare a description that lets the fault be reproduced outside the car. The part number alone is rarely enough, because diagnosis also depends on the vehicle, configuration…
After flooding, factory audio rarely fails in just one place. After contact with water, you must not test the equipment by switching it back on, because that is exactly when…
The OEM radio is usually the centre of multimedia and communication in the car, so a slow start affects more than the radio itself. If startup has clearly become longer, it is usually not about...
After disconnecting the battery, the radio, navigation or infotainment system may request reauthorisation. Most often the display shows CODE, SAFE, LOCKED, WAIT or ENTER PIN. Not every such message...
