There are two types of 2 pin connectors- Motorola and Kenwood ("everything else"). Everything else would include Baofeng, Midlands, Retevis.
If you have the correct Baofeng programming cable, you can set up the Baofeng/Retevis ' 16 channels. I think the Midlands are pre-programmed with 22 (I think) FRS/GMRS channels, so you won't have every channel.
Keep in mind that Baofeng is not compliant with FCC regs regarding FRS radios.
