Mail-in repairs, available throughout Poland
We diagnose and repair factory amplifiers, radios and navigation systems in MAN vehicles. We handle mail-in repairs and provide a warranty for the work carried out.
MAN
The models for this make are currently being added.
We also support devices not listed here — the list is published gradually, and our technical database is much larger. If you cannot see your make or model, call us or submit a quote enquiry. In 99% of cases we can help.
Are you trying to enter an address in the navigation, but half of the keyboard does not respond? Do you want to set a radio station manually, but the slider stops halfway and will not move any further?
No sound in a Ford Kuga, Escape, Ranger or Lincoln? It may be dry joints on the PCB of the Panasonic ACM module — not a radio replacement. Refurbishment 984 zł, 1-3 days, 24-month warranty.
No sound in a Mercedes W221 or W216? The Logic7 amplifier may be to blame. See why it fails, how professional refurbishment is carried out, and why it is worth repairing rather than buying a used unit.
Daiichi radio in Fiat Ducato shows WRONG PASSWORD and millions of minutes of lockout? A code generator will not help — we unlock by post in 1 working day, 297 zł with warranty.
Repair of MAN radios, navigation units and amplifiers concerns factory modules, i.e. components that work with the vehicle electronics, screen and audio system. That is why the same symptom may be caused by a radio fault, amplifier fault or memory fault, as well as by a power or communication issue. The driver sees no sound, a restart, a blank screen or a request for a code, but the cause needs to be identified. Before replacing a module, it is necessary to determine whether the unit itself is faulty or whether the issue lies in the vehicle’s wiring and configuration.
Symptoms linked to start-up, sound, the screen or a lock after disconnecting power may indicate a problem. In the vehicle, this may concern the radio itself, the navigation unit or the factory amplifier. A fault may be indicated by:
The same symptom does not prove which module is at fault. No sound may result from amplifier damage, a communication error or a short circuit in the speaker circuit. If the removed unit works correctly, the vehicle wiring should be checked by a local mechanic or electrician. In the event of a lockout, do not enter any more random codes, as this makes proper unlocking more difficult.
Diagnosis starts with identifying the module and describing the symptom accurately. For an enquiry, the part number from the label, a photo of the unit and a description of whether the problem concerns sound, start-up, navigation or a lockout are all helpful. We provide a free initial quote from photos and a description; response time depends on the completeness of the enquiry, the clarity of the photos and the type of module. The unit is sent only after you accept this initial assessment.
The removed radio, navigation unit or amplifier is brought in for checking; the workshop assesses the unit itself, not the vehicle. On the bench, we confirm the cause of the fault in the module itself, not in the vehicle wiring. If the unit turns out to be sound, the power supply, earths, connectors, aerial or loom must be checked locally. The scope of confirming the cause and the cost depends on the type of fault, the unit model and the tests required.
Repair only starts after the cost has been approved. Before being returned, the module is tested, and a written warranty is issued for the repair carried out; its scope and period depend on the type of repair. If, after refitting, the problem concerns the vehicle’s configuration or wiring, this must be checked locally.
Prepare the data from the label and a short description of the symptom, as this makes it easier and quicker to distinguish a module fault from a wiring issue or a lockout. With radios, navigation units and amplifiers, it is not only what has stopped working that matters, but also when the fault appeared. A lack of sound after a jump start is assessed differently from a blank screen after moisture ingress or after replacing the unit with another one.
A precise description helps link the symptom to the power supply, memory, panel or protection. Before shipping, prepare:
If the module has already been swapped, note this in the report straight away. Incorrect coding after fitting another unit can cause symptoms similar to a fault with the radio, navigation or amplifier.
When the damage is limited to the electronics themselves, restoring the original unit gives a more predictable result than swapping it for another one. This applies, among other things, to problems with the power supply, power stage — that is, the section responsible for driving the signal — memory, communication, backlighting or connections damaged by corrosion. A used module will not remove the cause if the symptom is due to the vehicle wiring or to a lack of configuration matching after installation.
The original module remains compatible with the vehicle if its functions can be restored without replacing it with another unit. This matters in the event of a lockout after the power supply has been disconnected, an error stored in memory or a previous unsuccessful intervention.
Swapping becomes justified in the case of extensive corrosion, mechanical destruction of the board or when the functions cannot be permanently restored. You then need to take into account that compatibility and later coding depend on the specific module.
Repair of MAN radios, navigation units and amplifiers: enquiry, module shipping and quote.
Yes, we work on MAN factory audio and navigation modules: the radio, the navigation unit and the amplifier. We do not repair replacements fitted instead of the original, such as Android units.
Repair lets you keep the factory unit matched to the vehicle and avoid the risk associated with a used module. You make the decision after the initial assessment, and we confirm the final terms after checking the unit.
First, we prepare an estimated quote based on photos of the unit and a description of the symptoms. After checking the module, we confirm the final scope, and the repair only starts after your approval.
The removed module is sent to the workshop, not the vehicle; you can send it from anywhere in Poland or deliver it to Sochaczew by arrangement. For shipping, protect the screen and connectors, use a rigid cardboard box and fill any empty spaces.
Prepare the make, model and year of the vehicle, a description of the symptoms and photos of the unit, the panel and the rating label. You do not need to know the radio model name; if the part number is needed, we will ask for it.
