Return, Refund & Warranty Policy

Last updated: September 8, 2026

Quick Summary

• 12-Month Warranty — Every complete head unit is covered for 12 months from the delivery date against manufacturing defects.
• Defective, wrong, or incomplete item? We cover return shipping and offer repair, replacement, or refund.
• Installed and working correctly? Once a unit is installed and confirmed to function as intended, we do not accept returns for change of mind, wrong vehicle selection, or buyer's remorse. Please confirm fitment before installation — see Section 2.1.
• Haven't installed it yet? If you simply changed your mind before installing, you have 30 days from delivery to request a return (buyer pays return shipping; item must be unused and resalable).

This policy applies to purchases from the ZENHAX online store operated by WONDFUL (HK) TECHNOLOGY LIMITED. It does not limit any consumer rights that cannot be excluded under applicable law.

1. 12-Month Warranty

All complete head units purchased from ZENHAX carry a 12-month warranty from the date of delivery, covering manufacturing defects and components that fail under normal use.

The warranty does not cover damage caused by:

• Incorrect installation, incorrect wiring, or use of tools/voltage not specified in the instructions
• Unauthorized modification, repair, or firmware alteration by a third party
• Physical damage, liquid damage, or damage from an accident after delivery
• Normal wear and tear, or a vehicle configuration that differs from what was confirmed with us before purchase

If a warranty issue is confirmed, we will offer troubleshooting, a replacement part, repair, replacement unit, or refund, whichever is most practical for the specific issue.

2. Return Eligibility

2.1 Before Installation — Change of Mind

If you have not yet installed the product and simply want to return it, contact us within 30 days of delivery. The item must be unused, complete with all accessories and packaging, and in a condition suitable for resale. Return shipping is the customer's responsibility in this case.

Please confirm your exact vehicle make, model, year, trim, and factory audio configuration with us before installing. This is the easiest way to avoid an unwanted install — once a unit is installed and confirmed working, it is treated as accepted per Section 2.3 below.

2.2 Installed Product — Defective or Not Working

If, after installation, the product does not function correctly, contact service@zenhaxauto.com within 30 days of delivery. Reasonable installation or testing needed to identify the problem does not by itself make the product ineligible for return. Once the issue is verified and the unit remains complete and in resalable condition (see Section 3), you are eligible for repair, replacement, or refund, and we cover authorized return shipping.

2.3 Installed Product — Functioning Normally

Once a unit has been installed and is functioning as intended, it is not eligible for return, exchange, or refund, even if you later decide you no longer want it, ordered the wrong configuration, or your vehicle has undisclosed modifications. This applies regardless of how the vehicle information was originally provided. We recommend fully testing all functions during a trial fit, before final installation, whenever possible.

2.4 Wrong Item Shipped, Missing Component, or Confirmed Vehicle Mismatch

If we shipped the wrong item, a listed component was missing, or you supplied complete and accurate vehicle information and we confirmed fitment in writing before shipment but the unit still does not match your vehicle, you are eligible for a return with shipping paid by ZENHAX.

3. Conditions That Make a Product Ineligible for Return

A refund or exchange is not available when customer-caused installation, modification, misuse, damage, contamination, missing parts, or other customer handling leaves the product unsuitable for resale, except where applicable law requires otherwise. This includes, without limitation: cut, spliced, stripped, repinned, or altered wiring; broken clips or mounting points; scratches, cracks, impact, or liquid damage; adhesive residue; missing accessories, cables, modules, labels, packaging, or serial identification; unauthorized programming or repair; and damage from incorrect voltage, tools, installation, or vehicle modification.

If a verified product defect or ZENHAX error exists, the case will not be treated as a standard customer-caused return solely because reasonable installation or testing was necessary to identify the issue.

4. How to Request a Return or Warranty Claim

1. Email service@zenhaxauto.com before sending anything back.
2. Include your order number, product name or SKU, vehicle make/model/year/trim, factory audio configuration, the issue you're experiencing, and clear photos or video of the product, connectors, dashboard, and packaging.
3. We will review your request and, where appropriate, offer troubleshooting steps first.
4. If a return is approved, we will send written return authorization, the correct address, and shipping instructions. Please do not send anything back before receiving this.

5. Response Time

We aim to respond to all support and return requests within 1–2 business days.

6. Authorized Return Warehouse

Recipient: XTECH+ADVM064
3263 Trade Center Dr
Riverside, CA 92507
United States
Phone: +1 (951) 742-5283

This is a fulfillment and returns warehouse, not a public showroom or our corporate office. Unauthorized, collect-on-delivery, or incorrectly addressed parcels may be refused or delayed. Please include your order number and return authorization reference inside the parcel.

7. Inspection, Refunds, and Exchanges

After an authorized return arrives, we will inspect its identity, contents, and condition and notify you of the result within a few business days. Approved refunds are issued to the original payment method; your bank or payment provider may need additional time to post the credit. A verified missing or defective component may be replaced without returning the complete product when that is the most practical remedy.

8. Order Cancellations & Delivery Estimate

Orders generally arrive within 7–10 business days after order confirmation. Contact us as soon as possible if you need to cancel — cancellation cannot be guaranteed once fulfillment or carrier handoff has begun. If an accepted order cannot be delivered within the stated estimate, we will provide the delay, cancellation, or refund options required by applicable law.
