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...

Just make sure that it's got all the wires connected... There are many "charging only" type cables for sale out there that will not function correctly in this sort of application.
