Do I need to replace the whole radio if it is locked or showing an SD error?
Usually not. Many battery-reset lockouts, radio code requests, and Map SD card errors can be fixed without replacing the full unit, depending on the exact model and fault.
What should I send before you check compatibility?
Send the model number, serial number, or a clear photo of the radio screen, label, or error message so we can confirm the correct solution before you order.
Which accessories and spare parts do you also offer for JDM systems?
We also support selected accessories and spare parts for Japanese multimedia systems after the main radio issue is solved.
- Android Auto & Apple CarPlay Kits

Can you help if my radio locked after a battery change or power reset?
Yes. Battery disconnects and power loss are some of the most common reasons Japanese radios ask for a code or stop loading correctly, and these are exactly the kinds of problems we help solve.
Can Bluetooth, FM, USB, DVD, or navigation return after the fix?
For supported models, restoring the correct unlock code, SD card, or recovery solution can bring back normal system functions that were blocked by the error.
Is the solution digital, remote, or physically shipped?
It depends on the radio and the problem. Some solutions are remote or code-based, while others need a compatible plug-and-play SD card or related media solution.
Can I order from outside my country if I imported a Japanese vehicle?
Yes. We help owners of Japanese import vehicles in many countries, so you can contact us online and get support wherever you are.
What if I do not know whether I need a radio code, a Map SD card, or language conversion?
Start by sending a clear photo of the screen or error message. We will check the model and point you to the right solution based on the exact problem shown by the unit.
