12-month limited product warranty

Gerllish Auto provides a 12-month limited warranty from the confirmed delivery date for manufacturing defects in covered products, unless a different written warranty period is stated on the product page or invoice. Mandatory legal warranties remain unaffected.

Support and claim procedure

Before returning a product, contact support with the order number, vehicle details, a description of the problem, and clear photographs or video. We may request safe troubleshooting steps, wiring checks, system information or diagnostic results. Do not return a product until return authorization is issued.

For a confirmed covered defect, the remedy may include technical support, software or configuration assistance, replacement parts, repair, replacement or refund as appropriate and as required by law.

Warranty exclusions

  • Incorrect installation, wiring, voltage, fuse or CAN-bus connection.
  • Use with an incompatible vehicle, accessory or third-party component.
  • Water, impact, fire, accident, corrosion, misuse or neglect.
  • Unauthorized disassembly, alteration, repair, rooting, software modification or damage to seals.
  • Normal cosmetic wear, consumables or accessories damaged after delivery.
  • Problems caused by incorrect vehicle information supplied by the customer.

Installation requirements

Professional installation is strongly recommended. Before cutting wires or permanently fitting trim, the installer must test power, sound, steering-wheel controls, cameras, CAN-bus functions and other relevant vehicle systems. Retain original parts and packaging until testing is complete.

Installation labour, removal costs, vehicle damage, loss of settings or data, towing, rental vehicles and other third-party costs are not included in this product warranty unless expressly agreed in writing or required by law.

Shipping for warranty service

Responsibility for shipping depends on the cause, destination and applicable law. Gerllish Auto will provide instructions after reviewing the claim. Do not send items freight collect or to an unconfirmed address.
