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.

Hi Midnight Blues

The fact is that under Garmin Spanner mode, Colorado 400 could connect to PC as a external GPS, which works fine with Google Map and nRoute, even Garmin Mobile PC can show satellite signal of Co 400 but not no other functions.
