Searching for CA-55 or CK9126 pop-port converter cable info

[hottroc]

Trying to wire up a pop-port plug to plug my Nokia 6810 into the HFU-2 control unit of my Nokia Cark-91 car kit (15-pin). There is a converter cable sold commercially as a Nokia CA-55, also seen as CK9126 (as it converts a Cark-91 into a Cark-126). But very expensive.

I know the pop-port pinouts and the Cark-91 but can't marry the two up.

Any help/info welcomed.

Same problem, can anybody help, please!?

I decided begrudgingly to order one after not getting any responses or help from anywhere. When it arrives I'll try to work it out.

Sorry, that last post was me, forgot to log in.

I have no good news  :( I've bought a CK9126 converter and tried to make some "reverse engineering" on it. But when I saw that PCB contains a PIC microcontroller gave up. I don't know PIC's, but im pretty sure it have some copy protection.
Maybe someone will make alternative version of converter...

Yes that was my thought too.
Somebody out there must have the ability to read the image off the PIC and work something out.

This really would help me out also.
Any advances?
Thanks

That's what I had to do in the end. Couldn't work it out, unfortunately.
