i used the same schematic for the Mazda, 1*LM3914 2* 7414 2*4066. my problem is everything its okay when the jack is not plug in the stereo, when i plug it i got just 2 buttons correct the others are completely wrong, any idea please, i used i diode still got the problem
Are you referring to my circuit in post #22 ?

Using the diodes to combine two outputs did not work, that is why they are scored out in the schematic sketch.
There have been other discussions about my circuit, have a look here:

where you will find the final version of the circuit.
