❓ Frequently Asked Questions

Is this compatible with my unit? +

This recovery SD card is strictly compatible with the specific JDM models listed. Check your screen model code (e.g. B9080, NSCN-W60) before ordering to ensure a verified fit.

Will this give me local maps or change the GPS? +

No. JDM multimedia units have built-in GPS tuners locked to Japan frequencies. This SD card is a recovery boot tool to unlock your radio, Bluetooth, climate controls, and settings. It does not provide local GPS navigation.

Can I choose between physical card shipping and download? +

Yes, we offer high-speed digital download links if you want to write the files to your own SD card immediately, or pre-loaded physical cards shipped to your door.

What if I am unsure of my model? +

Please take a photo of your radio screen (especially showing any error messages or model stickers) and send it to our support team on WhatsApp for immediate confirmation.
