hello all
i have citroen c4 picasso (2011 year), which cards do you recommend to put on it?
If you have any instructions on how to do it, I would be very grateful.

Hi grec,
First, identify your equipment, go to [Please Register or Login to download file] and enter your VIN code.
I think it's RT4/5.

My vin number is VF7UD9HR8BJ621662 , version information from multimedia settings is rneg_D_R29a_R29.01

when i put vin number od this link, he say MyWay (RNEG) Europa/Maroko - 2018-2 is latest ... it is old man. Did you have any solution for fresh map with central Europe map (serbia, bih, montenegro).

So it's clear, you know your GPS equipment. On my mind, RNEG was fitted until 2010.09.
For map updates, so there are no more official updates, look at unofficial updates based on BMW West Europe.
And you can update for RNEG Firmware R50b (R50.03).
