JapanRadios provides digital radio unlock codes and physical Map SD cards for Japanese Domestic Market (JDM) vehicles. Every order is covered by the guarantee described below.

1. 100% Money-Back Guarantee

If JapanRadios cannot provide a working unlock code for your radio, or if a supplied Map SD card does not resolve the reported issue, you may be eligible for a full refund under this Policy.

Approved refunds are returned to the original payment method used for the purchase.

2. Radio Unlock Codes

Radio unlock codes are calculated using the information provided by the customer, including the ERC string, serial number, radio model, barcode, or photograph of the radio screen.

A full refund may be issued when:

  • The information supplied was accurate and complete;
  • The code was calculated for the correct radio; and
  • The code does not work when entered correctly according to the provided instructions.

To verify that the code has failed and enable our engineering team to provide live assistance, the customer must contact JapanRadios via WhatsApp Live Support or through our Contact Us page and provide a continuous, unedited video showing:

  • The same radio for which the code was requested;
  • The radio screen and relevant identifying information;
  • The complete process of entering the unlock code; and
  • The result or error displayed by the radio.

Customers should contact us while attempting to enter the code so that we can provide live assistance and resolve the issue. We aim to resolve valid code-related problems completely before processing a refund.

3. Incorrect or Incomplete Information

If an unlock code does not work because the customer supplied an incorrect or incomplete radio model, ERC string, serial number, barcode, screen photograph, or other required information, JapanRadios will recalculate the code free of charge after the correct information is provided.

The customer must provide accurate information and any requested photographs or videos so that the correct code can be calculated.

4. Hardware or Compatibility Problems

Unlock codes cannot repair physical or electronic faults in a vehicle radio. Examples include a failed display, damaged buttons, defective internal components, wiring problems, power-supply issues, or other hardware faults unrelated to the unlock code.

If the radio has a hardware fault, compatibility issue, incorrect installation, previous modification, or another problem unrelated to the code, the code may not work even if it has been calculated correctly.

Customers should contact JapanRadios for live assistance before requesting a refund so that we can help identify and resolve the issue.

5. Map SD Cards

All Map SD cards are tested before dispatch and are guaranteed to work with the compatible vehicle and navigation system identified at the time of purchase.

If a Map SD card is faulty on arrival or does not work with the correct compatible system, JapanRadios may:

  • Replace the SD card; or
  • Issue a full refund.

To report a problem, contact us via WhatsApp Live Support or through our Contact Us page and provide photographs or a continuous video showing the SD card, vehicle navigation system, installation, and reported error.

The SD card must be used with the compatible vehicle and navigation system for which it was supplied. JapanRadios is not responsible for problems caused by an incompatible vehicle, incorrect installation, misuse, modification, damage, or use in a different system.

6. Delivery of Digital Unlock Codes

Unlock codes are delivered digitally through WhatsApp or email, typically within 10–20 minutes after successful verification of the information supplied.

Delivery may take longer if:

  • The information provided is incomplete or unclear;
  • Additional verification is required;
  • The radio requires additional research; or
  • Technical or communication problems occur.

We may request additional information, photographs, or videos before calculating and sending the code.

Because unlock codes are digital products, shipping charges do not apply to digital orders.

7. Delivery of Map SD Cards

Map SD cards are dispatched using express, tracked shipping.

  • The standard shipping charge starts at USD $70 for worldwide delivery.
  • The final shipping price may vary depending on the destination, package weight, package size, customs requirements, or selected shipping method.
  • Larger or heavier packages may require an additional shipping charge.
  • The applicable shipping charge will be confirmed before dispatch or displayed before payment.
  • Estimated delivery time is approximately 4–7 business days after dispatch.
  • Delivery times are estimates and are not guaranteed.
  • Delivery may be delayed because of customs clearance, carrier delays, weather, public holidays, incorrect address information, or other circumstances beyond our control.
  • Tracking information will be provided when available.
  • The customer is responsible for providing a complete and accurate delivery address.
  • Customs duties, import taxes, brokerage fees, and other destination-country charges are the customer’s responsibility.

8. Shipping Charges

Shipping charges are non-refundable, including express shipping charges.

Return shipping costs are also the customer’s responsibility unless:

  • The Map SD card was faulty on arrival;
  • The Map SD card was damaged before delivery;
  • The wrong product was supplied; or
  • The return is required because of an error made by JapanRadios.

For a faulty, damaged, or incorrectly supplied Map SD card, JapanRadios will cover the reasonable return shipping cost after the return has been approved.

Customs duties, import taxes, brokerage fees, and other charges paid by the customer are non-refundable.

9. Order Cancellation

You may request cancellation before a digital unlock code has been calculated or before a physical Map SD card has been dispatched.

To request cancellation, please contact us via WhatsApp Live Support or visit our Contact Us page.

Once an unlock code has been calculated or an SD card has been dispatched, cancellation may no longer be possible. In that case, the order will be handled under the applicable refund and guarantee terms in this Policy.

10. Returns of Physical Goods

Returns are accepted only for Map SD cards that are faulty, damaged, incorrect, or covered by the guarantee described in this Policy.

A Map SD card must not be returned until JapanRadios has approved the return and provided the correct return instructions and address.

Returned items must include:

  • The original SD card;
  • Original packaging, where applicable;
  • All included materials and accessories; and
  • Any other items supplied with the order.

We may refuse a return if the SD card has been misused, modified, copied, registered, damaged, or used in an incompatible system.

11. Return Authorization and Return Address

After reviewing your request, JapanRadios will provide return instructions and the correct return address.

Please do not send Goods to an address other than the return address provided by JapanRadios. Returns sent without prior approval may be delayed or refused.

We recommend using a tracked and insured shipping service. JapanRadios is not responsible for Goods that are lost or damaged during return shipping when the return is arranged by the customer.

12. Damaged, Defective, or Incorrect Goods

Please inspect your order promptly after delivery. If the Map SD card is damaged, defective, incomplete, or incorrect, contact us via WhatsApp Live Support or through our Contact Us page as soon as possible.

Please provide photographs or a continuous video showing the issue.

Depending on the circumstances, we may offer:

  • A replacement;
  • A replacement part, where applicable; or
  • A full refund.

Do not return a product until JapanRadios provides return instructions.

Damage caused by misuse, incorrect installation, modification, unauthorized repair, or accidental damage may not qualify for a refund or replacement.

13. Refund Processing

Once a refund is approved:

  • The refund will be returned only to the original payment method used for the order.
  • Refund decisions and approvals are typically resolved within 1–2 business days. Once approved, the refund is submitted to your payment provider within 1–3 business days. Your bank, card issuer, or payment provider may require additional time (typically 3–7 business days) to reflect the funds on your statement.
  • Original shipping charges are non-refundable.
  • Return shipping costs are non-refundable unless the product was faulty, damaged before delivery, incorrectly supplied, or the return was caused by an error made by JapanRadios.
  • Customs duties, import taxes, brokerage fees, and other third-party charges are non-refundable.

14. Exchanges

If a Map SD card is faulty or incorrectly supplied, JapanRadios may provide a replacement.

Replacement availability depends on stock and compatibility. Additional shipping charges may apply where the replacement is requested for a reason unrelated to a fault or error by JapanRadios.

15. Refused or Undeliverable Packages

If a package is refused, not collected, or returned to JapanRadios because of an incorrect or incomplete address, the refund will be processed only after we receive the Goods.

Original shipping charges and return shipping charges are non-refundable. Any additional costs charged to JapanRadios by the carrier may also be deducted from the refund.

16. Changes to This Policy

JapanRadios may update this Return, Refund, Guarantee, and Shipping Policy from time to time. Any changes will be posted on this page with a revised “Last reviewed” date.

The version published at the time of your purchase will generally apply to that order, subject to applicable law.
