REPLACE NG4 by 2DIN JVC or KENWOOD or PIONEER

[GEGEORLEANS]

Hello Everybody.
I own a 308 CC RR with NG4 systeme (without JBL option).
I am on the way to remove the NG4 for better facilities, BT streamming, tactile pannel, DAB+ etc.
I installed new speakers for better sound quality (front and rear ones).
I bought the connects2 SPG013
Everything (except can bus issue) works perfecty. The new sound is fantastic and GPS so easy to use.
The big issue is that the fact to remove the NG4 (already desactivated il all bsi and other calculators options) show the ALERT message. "vehicule must be repared' (or something like that; I am French in french version) and the system is in the degraded mode without turbo and high gazolin waste.
Maybe it is beacuse of the lack of information pannel? Do you thing if a install an EMF C (real node) my problem will be resolved?
Kind regards.
Jerome.

Can you confirm what year your car is?

I forgot to write, CAN BUS issue is U0140 issue - BSM-BSI communication issue, something goes wrong if I remove the NG4. If I plug again the NG4 the permanent default desapears.
I did the PSA procedure to remove the device. (battery disconection with the differents steps to wait before an action)

The year is 2012.
