I'm a polo 9n fan and I have installed on my car an MCD navigations system VW and now I would like to send the navi and radio information to the FIS dispaly on the tacho.
In any post POLO16v said that simply connect the can l and can h of the navigation system to the canh and canl pin to the tacho whit a twister wire shield.
navi tacho
CAN h-------------------> Can H (comfort line)
CAN l -------------------> CAN L (comfort line)
I's all right.

Please help me.
