Wrong headunit?

Unread post by r0ckerdude44 »

Hello
I recently purchased a c4 grand picasso which has a RNEG head unit with limited functionality.

The headunit only has french language and i am not able anywhere in the menu to change this option.

Also the gps antenna does not work (no signal) and there is no trip computer available (with mpg and other info).

With the help of a friend I figured out my 2012 c4 grand picasso came with a rneg head unit.
I extracted the headunit and checked the part number from it but it shows it is a c5 headunit (maybe this is why it does not show trip computer and navi is stuck?)

With the help of another friend we looked in diagbox to see if there is any option regarding the trip computer but there is none.

Please could you help with any advice? I just want it to work like default from factory.
