What we actually do, and the one mix-up worth clearing up first.
Navigation Unlocker is a worldwide, freelance-based consultancy and information portal for Japanese car multimedia unlocking. We’ve assisted people in over 50 countries, and we work through a network of dealers, technicians, and radio mechanic shops around the world — arranging support and services once specific terms and conditions are met. We do not sell products directly, in Bangladesh or anywhere else.
About the word “Navigation”
In Japan, the whole in-dash stereo system is called the “Navigation System,” because the map function is built for Japanese roads. When these units are imported — reconditioned or second-hand — into other countries, that map stops working, and other functions often lock up with it: FM channels, Bluetooth, CD/DVD, even the back-up camera. We don’t unlock car navigation maps themselves; we help unlock the multimedia system around them. We do not unlock Map functions and we do not do language change.

SD card CID edit device — one of the tools our network uses for reprogramming.Remote guidance
Whether your unit needs a re-flashed SD card, a password reset, or a full mapdisk reprogram, our contacts have the devices and software to do it. You send the details of your head unit; we route you to the right solution and the right person to run it.
Consultancy and training are also available if you’d rather learn the process yourself, or you’re setting up a service business of your own.

WhatsApp and Viber get the fastest reply — usually within a minute. Email works too, if you’d rather write it all out.
Support and service is not currently available in Bangladesh. We hope to launch there soon.
