the code depend on the unit itself or car and there are LOTS of phillips car stereos so how are we supposed to know?
You can try (ive done it before) to do this...
If the code is 1435, for example, press #1 BUTTON once, #2 four times, #3 three times and #6 five times. get my drift? Dont try it more than twice because it may disable you from trying after that.Entering a pin code into my Philips Car Stereo System?let say the code is 5812
you only use the four pressets
memory
1 press 5 times
2 press 8 times
3 press 1 time
4 press 2 times now the radio will display 5812 press the am fm or power button and radio will turn on
good luck
