What we diagnose
This is 12-volt work. We find why the electronics failed — not a check-engine guess and not a parts-cannon. Tell us the year, make, and model or the VIN and what it is doing. We source the fitment, then we test.
- Head units and factory radios — no power, no sound, boot loops, lost steering-wheel controls, Bluetooth that dropped after a battery change.
- Amplifiers and speakers — amp in protect, one dead channel, distorted bass, factory amp that died after a stereo swap.
- Cameras and dash cams — blank screen, parking-mode drain, camera that worked until someone tucked the harness.
- Key fobs and immobilizer-related fob issues — dead battery vs failed fob vs a programming problem. Battery is $15 if that is all it is.
- Aftermarket lighting and 12-volt extras — circuits that backfeed, blow fuses, or throw bulb-out errors.
What we do not diagnose
Engine, transmission, hybrid high-voltage, airbags, and body-control modules that are not tied to audio, cameras, lighting, or fobs. If you need a mechanic, we will say so. If it is the radio, we will not send you to a dealer.
How a visit works
| Step | What you get |
|---|---|
| You tell us year/make/model or VIN | We look up the real system, not a catalog guess |
| We test in the vehicle or on the bench | Power, ground, speaker loads, data, and the part itself |
| We quote the fix before we start it | Repair, replace, or leave it — your call |
