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.

Regards

If Mobile PC is connected with Colorado, only problem can be that program is not unlocked.

Files "sw.unl" and "gmapsupp.unl" should be placed together with "gmapsupp.img" in Mobile PC installation directory (C:\GarminMobilePC).

For generating sw.unl file use code from Mobile PC -> Settings -> About -> Software Unit ID.

Use [Only registered and activated users can see links. ] to generate code and [Only registered and activated users can see links. ] for writing unl file. In keygen select Garmin Mobile PC from drop list.

Hi Midnight Blues

Thank you for reply.

Last night I've generated the sw.unl file by the tools you mentioned, and tried the software unit ID and Colorado ID, none of them work, do you think this will be the keygen issue?

The error message is
could not authenticate garmin GPS hardware

So I think it's not related to maps, but the device.
