## Navdy Firmware
|
|
|
In January 2018 the company behind Navdy closed its doors. The community of users were then left without any further support for the heads up displays we all use and love.
|
|
|
|
|
|
Shortly after, a number of features in the display and phone apps started to fail due to the online services they relied on shutting down, and/or accounts expiring.
|
|
|
A number of users on reddit started sharing on how to get around these issues, gradually growing over the coming months into complete replacements for the broken features through patched apps and eventually this rebuilt firmware.
|
|
|
|
|
|
For the last couple of years now I've been releasing hacked Display Firmware and Android app under the alelec headings. I've got no relation to the original Navdy company and can only work on this in spare time, but will endeavour to continue to help navdy users get the most out of the HUD.

### Original Firmware
|
|
|
As of 1st Jan 2020 all original navdy firmware finally stopped being able to show any kind of maps at all on the display. My firmware releases older than this also failed in the same way.
|
|
|
|
|
|
In most cases the display would start up and just show ["Display update required"](https://www.reddit.com/r/navdy/comments/es5hbt/howto_fix_the_display_update_required_shutdown/)
|
|
|
On some version of the original navdy firmware this screen wasn't shown however, but instead simply won't show maps on the screen.
|
|
|
|
|
|
It's caused by the original navdy login keys for the Here navigation service expiring without warning, meaning the display maps engine cannot start anymore.
|
|
|
|
|
|
The only known way to fix this is to update your navdy to one of my unofficial firmware packs, there's no way to update the keys in the official firmware pack.

## Firmware Installation

The current recommended stable version is 3093.

### Install instructions
|
|
|
|
|
|
As yet my firmware cannot be installed via the phone app, it needs to be installed via PC over a micro-usb cable.
