Thread: Colorado 300 ( partial software after failed update from 2.90 to 3.70)

Odd thing is , whatever i try , no maps show up.

In basecamp it sees basemnap and openmtb map, but device itself does not show any map, neither detects any of cards i have.

Anyone got 2.51 gcd file for dervice?

Somehow jawava reports device has 2.51 software, while device itself reports 3.70
jawava did updated to 3.70, now mass storage is accessible normnal way , hold up button and plug USB.
With any lower version it will only boot to mass storage with 066101000230.rgn (cure image)


And GPS Software is reported 2.90 (Netherland's GPS forum mentioned 3.0 update avail for devices suffering incorrect device Date/Time - mine shows 1. Jan. 2000)

Any more hints, how to solve it ?

Arvi has been banned from forum it seems, and sort of is unreachable by gsm (all busy signal - prolly me blacklisted...)


EDIT Reason additional questions:

After looking in to BIN files, Nüvi has fw1_resource.bin as well while extracting GCD file, while Colorado does not have it.
But on Reset this Language "Õ" is displayed , i start suspecting some part of firmware is somehow gone…
