Solving Aftermarket Headaches, One Vehicle at a Time

If you’re responsible for a fleet of vehicles that have had various aftermarket systems fitted—whether by dealers, previous owners, or third-party installers—you’ve probably run into a familiar problem: what do you do when something goes wrong? Who do you call when the dash is a mess, a monitor stops working, or a camera feed goes blank?

At Fir Tree Technology, we specialise in solving exactly these challenges.

With over 20 years of experience working across all major vehicle brands and aftermarket systems, we’ve built up the technical know-how and industry contacts to identify, diagnose, and resolve issues others won’t touch.

How Does It Work?

1. Tell Us the Problem

Let us know what’s wrong. Whether it's a non-functioning dash camera, a blown inverter, or a mystery switch left behind by a previous installer—we’ve seen it all. Just tell us what the issue is and what kit is involved (if known).

2. We Assess and Survey the Vehicle

Our team will carry out a full inspection of the affected area. We assess how and where the existing equipment is installed, how it’s been connected, and what impact it's having on the wider vehicle systems.

3. We Advise on the Best Course of Action

Once we understand the issue, we’ll provide clear guidance on what’s needed to get it sorted—whether that’s a simple reconnection, a rewire, or full kit replacement.

4. We Fix It—Properly

Depending on the situation, we may:

  • Source a like-for-like replacement from the original kit manufacturer
  • Recommend a better alternative from a more reliable supplier
  • Design and manufacture a custom solution ourselves to overcome poor previous installations or compatibility issues

Our Goal: Clarity, Reliability, and Fleet Uptime

We don’t just fix what’s broken. We help you understand your vehicle setup, offer a single point of contact for future issues, and ensure every fix is clean, tidy, and reliable. If you’re tired of patching problems left behind by others, talk to us.

Whether it’s legacy kit from a used vehicle purchase or a fault no one else wants to take ownership of—we can help.
