I thought I'd offer this feedback:

I coded a friend’s M3 this afternoon with NavCoder. He had recently installed a 16:9 screen, a BM24 radio and a 16:9 TV module, in substitution for a 4:3 screen, a BM53 radio and a 4:3 TV module.

He had split screen in all modes, including radio.
He had no telematic data.
INFO and SEL keys were not working.
Languages were to his liking

I coded in the car’s VIN, and selected BM24. I did not code languages. The result was:

Split screen in all modes, except radio.
Telematics data OK
INFO and SEL keys working
Languages as before (OK).

Now the question is why did we loose the radio split screen? He had it before coding so it is obviously possible to have it with his configuration. But there is no option in NavCoder to choose BM24 radio together with radio split screen.

Is there any way to recover it?

Thanks
