Garmin HUD Got Discontinued, But Not Trashed

The Garmin HUD+ was a modest Bluetooth machine supposed for the dashboard of a car, intended to be employed as a GPS heads-up display screen for details from Garmin smartphone applications. It used a brilliant VFD (vacuum fluorescent display screen) which was considered as a result of a clear reflector, and displayed GPS details and instructions. It was discontinued in 2015, but [Doz] was fond of his and utilised it happily right up until a cell phone upgrade meant it no more time labored. Was it destined for a landfill? Not if he experienced anything at all to say about it!

The initially point [Doz] experimented with was making use of an alternate Android app, but because it also didn’t work, it was time to sit back and mirror on the scope of the issue. In [Doz]’s circumstance, he actually only wished some basic meaningful info shown, and made a decision he could do away with the phone completely if he experienced the proper hardware.

A GPS receiver and ESP32 board take the location of a cell cell phone application that no for a longer time functions. The HUD exhibit alone is unchanged.

A u-blox GPS module and ESP32 board have been the keys to producing a standalone system to display screen significant information on the Garmin HUD+ over Bluetooth, many thanks to the simple fact that the protocol utilized experienced been reverse engineered. After a large amount of troubleshooting, [Doz] bought some simple functions performing: speed, time, satellite count, and a doing work compass arrow. The GPS receiver and ESP32 dwell in a compact 3D-printed enclosure, and the HUD? It stays on the dash just like it generally has, for good in 2015, blissfully unaware that the march of smartphone technological innovation has left it powering.

His code is on GitHub and there is a video clip demonstrating the the unit embedded down below, just beneath the site break. It’s constantly pleasant to see VFD shows supplied new lifestyle.
