GNC255 Database updates

[Leo Langston]

I recently got a used GNC255 installed in my panel. I got Garmin to allow me to add the 255 to the rest of my Garmin avionics so I can update the frequency DB. What sort of USB connector do I need to perform this update. What type of USB port does it have? I didn’t get any special USB cables with the unit when it was installed.

Thx
Leo

IIRC, you need USB 2.0 Micro USB-A Male to USB-A Female Adapter.

What type of USB port does it have?

If I recall correctly, the GNC255 has a USB Micro-AB (2.0) receptacle.

What is the difference between Micro A and Micro B USB?

What is the difference between Micro A and Micro B? Type A plugs are typically used to plug into a “master” device, such as a computer. Type B plugs connect to a “slave” device, such as a printer or cell phone. A micro-B receptacle will only work with a micro-B plug. A micro-AB receptacle...
