Frequently asked questions and answers
Repair of radio, navigation and amplifiers for Alfa Romeo 159: submission, module shipment and quote.
Do you repair the factory navigation system from the Alfa Romeo 159?
Yes, we service the factory Magneti Marelli navigation systems from the Alfa Romeo 159 after receiving the removed unit. We do not repair Android replacements; we identify the original unit by the part-number label.
Where can I get the navigation code for the Alfa Romeo 159?
The code is stored in the memory on the navigation's main board. We read it from the removed unit running on the bench, so the navigation system needs to be sent to us or brought in.
How is the quote for the Alfa Romeo 159 service calculated?
We provide an initial quote before shipping, based on photos of the unit, the label and the symptom description. Once we receive the module, we check it, confirm the scope and cost, and wait for your approval.
Do you need to bring the car in, or is just the navigation unit from the Alfa Romeo 159 enough?
Just the removed navigation unit is enough, sent by courier from anywhere in Poland or delivered in person by prior arrangement. Removal and refitting in the car should be carried out by a local workshop.
What should I prepare before submitting a navigation unit from the Alfa Romeo 159?
Prepare the car's year, a description of the symptoms, and photos of the screen, the front of the unit and the label. Let us know whether the navigation system has been in the car since new or comes from another vehicle.
Repair of Alfa Romeo 159 radio and navigation covers the factory Connect NAV and Connect NAV+ navigation units used in this model.
Which devices do we repair in the Alfa Romeo 159?
In the Alfa Romeo 159 we repair Connect NAV and Connect NAV+ units made by Magneti Marelli. These are factory radios with navigation, protected by a four-digit code.
How can you tell the problem may be in the module?
These navigation units arrive for service showing the "Master Code Request" screen. Shortly after the ignition is turned on, the unit asks for a four-digit code and without it you cannot use the radio. This happens in three situations: after disconnecting the battery, after buying and fitting another navigation unit of this type, or when the radio code was never included in the car documents. The navigation compares the chassis number read from the car with the number stored in its memory — if they differ, it asks for the code.
Repair scope and practical information
The code is stored in the memory on the navigation unit's main board, so we need the unit removed from the car to read it. We power it up on the bench and read the original code. In your enquiry, please tell us:
- the car make, model and year,
- a photo of the screen with the message,
- a photo of the front of the unit and the label with the part number,
- whether the navigation unit has been in the car from new or was purchased separately.
If your unit has a different fault, describe it — after looking at the photos and your description, we will tell you whether we can accept it for checking. We do not repair Android replacements. We confirm the price and scope of work before we start.
