Tomtom bluetooth lead

[Joca]

Hi. My first new thread,
I have bought a used tomtom V1 and the lead from the bluetooth unit to the helmet headset is missing. I am looking for some info on it
I know it is a 2.5mm jack at both ends, is it 3 part or 4 part jacks. And how long?
If anyone has one spare, even better....
TIA

No one has one? I still need this info...
