I built the small circuit to receive directly from the radio to the tablet, but it doesn't work, where am I wrong?

I built a cable according to the circuit in the manual
and that works. 99% of all tablets using the 'CTIA'  plug scheme. You have to check before
- does your tablet support a mic input like that ? Any headphone & mic that comes with a
mobile phone will help to find that out.

I sacrificed two good cables, because soldering on a plug (like the one on the left of the picture) is very difficult.
