Warranty and Maintenance Policy

Product warranty.

Vinh Hien warrants that the products supplied are newly manufactured devices, free from any defects at the time of handover and installation.
Warranty period (from the date of purchase): depending on the device type and the terms of sale, the warranty terms are set out in the equipment purchase contract.
If you require warranty service, please contact our Customer Care line at 1900-1522 / support@vinhhien.vn and make your vehicle and device available for a scheduled inspection and warranty appointment. We will respond and inspect the product within 24-48 hours, excluding days off and public holidays. Please provide proof of purchase (such as a receipt or handover record) and documents demonstrating that you are entitled to warranty service.
Vinh Hien GPS is not liable for any injury or damage, direct or indirect, to people, animals, or property arising from failure to follow the safety instructions in the user manual, particularly in matters relating to the installation, use, and maintenance of the device.

Proof of purchase can be provided (handover record, acceptance record, installation contract, etc.).
The warranty seal on the device is intact.
The device is still within its warranty period.
Vinh Hien will repair defects covered by the warranty without any additional charge, within a reasonable time after being notified of them. Before carrying out repairs, Vinh Hien — through its authorized technicians — will determine whether the defect falls within the scope of the warranty.
Any service performed on the device under these warranty terms does not extend or expand the warranty period or the scope of the warranty.

Defects determined to result from improper, negligent, deliberate, or careless use or storage (for example, failure to follow the device's user instructions).
Defects determined to result from improper self-installation (such as connecting an unsuitable power supply), from maintenance or repairs performed by unauthorized persons, or from damage in transit.
Poor performance caused by the use of replacement parts not supplied by Vinh Hien. We will permanently refuse warranty service for devices that have been disassembled or had components replaced by parties not authorized by us.
Damage caused by lightning strikes, damp or mould, fire, unsuitable voltage, an unstable power supply, poor earthing, or other causes not attributable to the manufacturer.
