Why owners choose us

A workshop that does one thing properly

We are not a general auto-electrician. Peugeot and Citroën navigation electronics are all we do, and it shows in the results.

Specialist focus

Years spent on the same families of units means we recognise most faults on sight.

Component-level repair

We replace the failed part on the board — not the whole unit — so you keep your original coding.

Fixed quotes

You get one clear price after diagnosis. No surprises, and no charge if we cannot help.

Worldwide postal service

Customers on five continents send us units every week. Clear packing and return instructions included.

6-month warranty

Every repair is covered for six months from the date it leaves the workshop.

Fitting & coding help

Remote support to get the unit back in the car and talking to the rest of the vehicle.

How it works

From fault to fixed in five steps

Most repairs are back with the customer within two weeks, including international shipping both ways.

  1. 01

    Tell us the symptoms

    Send your VIN, the unit type and a description of the fault through the contact form.

  2. 02

    Get your assessment

    We reply — usually within one working day — with a likely diagnosis and packing instructions.

  3. 03

    Post the unit

    You remove the unit (we can guide you) and send it by tracked courier to the workshop.

  4. 04

    Repair & bench test

    We repair at component level and run the unit under load for 24–72 hours to confirm the fix.

  5. 05

    Back on the road

    The unit is returned by tracked courier with a 6-month warranty and refitting support.

Turnaround from receipt of the unit is typically 3–7 working days.

Testimonials

Trusted by drivers and independent garages

Told by my local Peugeot garage that the RT6 unit needed replacing, I found no one who could repair it — then I came across Autotronics. Karim repaired the original fault, updated the unit and fixed the faulty CD drive as well, at a very reasonable price, then helped with refitting. If you have a faulty RT unit, do not hesitate.

The radio in my Citroën C5 would not work and kept asking for an upgrade CD. A Citroën garage and a radio electronics company both failed to fix it. I sent it to Autotronics on the Monday and had it back a week later, fixed and updated. Great service — Karim was very helpful.
MartinIreland
I sent the satnav media unit from my Peugeot RCZ for repair and it came back working perfectly. Being in Australia I had real difficulty finding anyone, but Autotronics were a great help. Highly recommended.
Darren McK.Australia
Superb service. Karim fixed my Magneti Marelli player within two days and it did not cost a fortune. Peugeot wanted almost €2000 to replace it. If you have one of these faulty units, Karim is the guy.
Gary AshtonMalta
Brilliant service repairing my Peugeot 508 CD/satnav head unit. I sent the box from the UK and it was returned fully repaired within two weeks. Highly recommend for any Peugeot or Citroën head unit issue.
Mark TompkinsUnited Kingdom
RT6 satnav problem where nothing worked properly and Peugeot could only suggest a new unit. The repair took less than two weeks including shipping to Spain and back. The system now works perfectly.
