RD4 to RT6 after build in problems.

Hello all im a owner of a C3 2011 car that came with an RD4 unit.
I bought a RT6 that came from an wrecked C3 2015 model and i built it in to my car, i used the pinout for the rt6.

Now the radio works fine GPS working and he gets the info from can correctly as he shows doors open etc.

The following problem i have is an annoying BEEP every two seconds no matter what i do. The only way to put the sound off is push the power button so radio shuts down and only navigation is on with sounds turned off, if voice turned on the beep comes back.

My parking sensors wont work when putting gear in reverse.

I try to update the last firmware downloaded from this site only he wont read the usb it will say checking file and it will take over 30 min. Formatted in FAT32.

Does anyone have any idea for this problem or suggestions for what i can do?

I bought a new USB and im gonna try to update with this usb to make sure its not a faulty usb.
