Yeha, great info Kiwi...thanks a lot.
In fact, navi seems doesn't communicate with central unit anymore.

Do you really think, in your experience, trying with a mode2 burnt cd my navi comes alive?
Hi great

Hi Jammy
it's true, above v22, sw version doesn't change.
Thnks

Yes, your Mk3 will come alive again.

Get these tools:

1. mode2cdmaker v1.5.1 from http://es.geocities.com/dextstuff/mode2cdmaker.html
Get the binary file, you don't need the source files.

2. Also get the GUI from UbiK v1.6, at same place.

3. Get ImgBurn from http://www.imgburn.com/

Install all of these. Then you need the modified mode2cdmaker.exe from me. The modified version writes the correct TOC. I can email this to you. Replace the standared mode2cdmaker.exe with the new one.

Then to make a good Mk3 OS CD:
1. Use mode2cdmaker to make a new disc image.
Use these options:
Do not set FORM2 (files names not bold)
File names = ASCII
Single Track, Keep Extension, View Prompt = all not ticked
Image type = BIN/CUE
Volume name = NAV_OS (important!)
Form2 ext = dat

2. Burn and verify the image with ImgBurn. Burn at slowest speed. Use a slow speed CD-R only. Mk3 cannot read CD-RW.

When you open your image with ImgBurn, before you burn it, it will show
Sectors: xxxxx (MODE2/FORM1/2352)

Hopefully you will get zero errors after the verfiy, but I had 9 errors with my media, but OS still worked OK.

Symbian, it worked in my case, nav unit is back up and running with v22.1 software. Lods of people have talked about sending their units off to somebody to fix, I wouldn't be surprised if this isn't all that they disk!

Jochen, I replied on your other thread, but reading this now looks like I need you modified mode2cdmaker, hence the reason it failed first time round! You say you have 3/1-64, so if I have v22.1 then I need to modify any later version to at least 3-1/64 for the update to be recognised? At the moment it just spits the disk straight back out. I'll PM you my email address if that is ok.

thanks

This should say:
Volume name = NAV_SW (important!)

But it is correct in your other instructions. And yes, it does work

Oops - sorry everyone, Jammykam is right. NAV_SW for the OS disk, NAV_DB for the map data disk

Will MAP/ROADMAP CD-R's with MODE1 will work on MKIII or must that be also MODE2 ?

Map can be Mode1 although i note originals are actually Mode2.

Can someone help me?
I have followed the procedure described above but when I insert the cd he immediately goes out.
I am sure not to have mistaken anything!
I have created the image with m2cdmgui.exe as described by Jochen and then burnt with ImgBurn but nothing, it doesn't work.
