could not authenticate garmin GPS hardware

The Device ID I used is the one in the Settings -> About page, not the ID of my Colorado 400c.

Any advice?

Hi,

Let's clear out some facts.
Colorado 400c is stand alone GPS navigation device and Garmin Mobile PC is Windows PC program for navigaton.

To navigate with Garmin Mobile PC You need USB, serial or BlueTooth GPS reciever connected to Your PC (not GPS navigation device).

To transfer maps to Colorado 400c You need MapSource program (not Mobile PC), or You can copy gmapsupp.img to memory card (with gmapsupp.unl).

In both cases You need key generator, for Mobile PC to unlock program and maps (sw.unl and gmapsupp.unl) and for Colorado 400c only to unlock maps (gmapsupp.unl).

What do You want to do???

You could not use Colorado 400c as external GPS reciever for Garmin Mobile PC program.
