> Restore a GoClever GC-4366FMBT GPS by reinstalling its firmware from an SD card and setting up Mireo viaGPS Black Edition 3.1.

My broken [GoClever GC-4366FMBT](http://old.goclever.com/en/gps/108-GC-4366FMBT-FE.html) GPS had been collecting dust for a long time, so I decided to bring it back to life.

That meant removing GeoShell and a cracked copy of Garmin that used PortSplitter. That setup had stopped the original Mireo navigation software from working: it crashed at the **Attaching GPS...** message while loading.

After several unsuccessful fixes, I decided to reinstall the GPS firmware. It took a lot of searching, well beyond the first page of Google, and plenty of trial and error. Eventually, I found suitable firmware for the GoClever GC-4366FMBT, Mireo Black Edition 3.1, and maps for Bulgaria, Romania, Greece, Macedonia, and Serbia. Now the GPS works again :)

Here's how to reinstall the firmware and set up the navigation software.

## Firmware installation

Before updating the firmware, back up the `MobileNavigator` folder from `Resident Flash` so you can restore your existing navigation software afterwards.

1. Download [GoClever-GC-4366FMBT-Firmware.zip](https://drive.google.com/file/d/0B7fdeNpb7YxONGZCZ0tYVW5wQzg/edit?usp=sharing) and extract it.
2. Copy the contents of the archive to an SD card, then insert the card into the GPS.
3. Turn on the device. It will boot and start updating the firmware.

4. After a few minutes, the update will finish. The device's default language will be Polish. To change it, select the settings icon, then the language icon.

Delete the firmware files from the SD card afterwards; otherwise, the update will start again the next time you turn on the GPS.

## Mireo viaGPS v3.1 installation

After the firmware update, I had to reinstall the navigation software because I hadn't backed up the `MobileNavigator` folder.

1. Download [Mireo viaGPS Black Edition v3.1](https://drive.google.com/file/d/0B7fdeNpb7YxOVmJzekdjcDVGMFU/edit?usp=sharing), which includes a detailed map of Bulgaria, and extract the archive.
2. Rename the extracted folder to `MobileNavigator`.
3. Copy `MobileNavigator` to `Resident Flash` or your SD card.
4. Start the device and select **Navigate**.

That restored my navigation software and maps.

The [map archive](https://drive.google.com/file/d/0B7fdeNpb7YxOdDZJUEJHYnBOSWM/edit?usp=sharing) contains detailed maps of Bulgaria, Greece, Romania, Macedonia, and Serbia dated June 2012. With some searching, you may also find a complete map of Europe from the same date.

**Note:** The license for the 3D maps in the archive above doesn't work.
