Hi people,

I have a Navcomputer partnumber: 6590 6922720-00
I think it is monochrome but i am not sure its mk3 or mk4
I can't get it coded for color monitor and now im doubting about the version!
When i read the unit with navcoder it says mk1,mk2,mk3 but based on this number and after a search on the net its listed with the mk4

I tried to convert it to color with the modified cd's for mk3/mk4 as written by Kiwijochen but wenever i put in a modified os disc it keeps spinning and im having a hard time to get them out, after that i cannnot read nav settings with navcoder until i reload an original os disc (not modified)

So i'm stuck and don't know what else to do
The modified os disc for mk4 i downloaded here but could not get it to write in mode2/form1
The modified os disc for mk3 i modded myself following the instructions in this forums and are written in mode2/form1

Desperatly seeking help

Friendly regards

Joël
