BMW car phone - Send Recieve Module

Projects General Guidance
1

Hello all,

I have BMW Car phone which only work 900Mhz, I currently life in Holland where they don't support that Frequency anymore, it's an old Motorola system 1998.

Now I know that there are (a lot of) Arduino Phone Shields available.
Is it possible to integrate this for my old Motorola, keeping my old function, like display and input.

Thanks in advance.

Hello,

I think you can do reverse engineering to decode how it communicates with ibus system. However I dont see any point to use it again, as phones in cars are quite outdated.
