Mondeo MK4 radio keycode entry buttons not working

[Dave80]

Hi All, i have a Mondeo MK4 where my head unit stopped powering up so i have purchased another identical head unit and i have the code for it, i have fitted the radio and when it asks for the code none of the buttons work, and then sometimes the number 1 button will work but no other buttons will work, not even the delete option,i have searched but not found any instructions on any special way to enter the code on this perticular head unit, i will list the things i have tried so you know what it isn't, i will also show a picture of the head unit.

 

*press buttons and nothing happens.

*pressed button 1 for code number entry 1,then pressed 1 again to increase the 1 to a 2 or higher, the 1 just goes to the 2nd code entry so i have 1-1.

*tried the above and tried using the volume up and down switch to increase/decrease the number, nothing happens,tried the skip forwards/backwards to increase/decrease number, nothing happens.tried the up and down switches on the steering wheel nothing happens.

*Instead of pressing 1 first i have tried pressing other numbers and nothing happens.

*i have powered the car off and tried the above, i have had the key in all ignition positions and tried the above.

*i have pressed button 1 to enter the first number of the code (which is 1) then pressed the next number and nothing happens.

 

if anyone has the same radio and has the same issue or knows exactly how this one needs to be entered i would be forever thankful for any assistance.

As it's a used unit, I suspect it's been damaged in transit.

Should just press each number once to enter the code on these.

Its not been damaged in transit as i picked it up myself from the car it came from.

Did you check the numbers worked before removal?

[Dave80]

no the battery was dead on the car.

This is what the manual says:

 

ENTERING A SECURITY
CODE
If CODE - - - -, CODE 0000, SAFE or
ENTER KEYCODE appears in the
display when you switch on the unit, you
must enter the Keycode using the on
screen instructions.
Use the number buttons to enter the
correct code. Press the button below OK
to confirm the entry.
INCORRECT SECURITY
CODE
CAUTION
Make sure that you have entered the
correct Keycode before confirming
the entry. Repeated incorrect entries
may cause a permanent lock of the unit.
Up to three Keycode entry attempts are
allowed before the unit will lock for one
hour

thanks ris but i have that manual and tried that but it didnt work, thats where i found that other models have different ways of entering the code

I think the simplest reason is that the unit you purchased is sadly faulty....

My 1st port of call would be a return visit to the seller and hope they don't wash their hands of it.

[Dave80]

So a bit of an update, i have changed the whole button assembly (from my original unit which i know for a fact worked) into the new radio to cover any possibility that the buttons are faulty, and when i say the whole assembly i do mean the whole assembly, and great news, its done nothing, the same thing is happening so i know it isn't faulty buttons, i will show pictures of the parts i changed.

 

IS THERE ANYONE WHO HAS THIS EXACT SAME STEREO THAT HAS ENTERED A CODE????? i cant help but think there is an unusual sequence that needs to be used.

 

On the chance that it is a more internal issue i am going to be trying the following things;

*Swap the new radios screen to my old radio parts to see if that powers up, if not then..

*swap the power pack part of the old radio for the power pack part of the new radio.

Try this old Ford code entry method.

Ignition fully on (engine not running).

[unofix]

Just realised that the unit you have is the Travelpilot. Try this method:

[Dave80]

Thanks unofix, I have tried both of those ways and neither has done anything, still stuck with only the number 1 being active sometimes.

Then I have to say I think your replacement unit is just as dead as your original. 🙁

Looks like you need to get one of the units sent away for repair.

update, SUCCESS!!!! EUREKA!!!! TFIDI (thank f@~# i did it.)

 

ok i now have a working radio and i will go through the process that brought me success,

*first of all there is no clever sequence.

*second it appears i did have 2 faulty units but swapping the right parts is what brought the success.

*my original unit the large part of it, the power pack part i am calling it was defo dead.

*the part that was faulty on the new unit was one of the circuit boards which i will show with a picture.

*the buttons were not faulty on either unit.

*i am unsure if the screen on my original unit is faulty.

*i have taken the button assembly from my original unit, the circuit board that attaches to it from my original unit (this is they key fix piece), the screen from the new unit and the power pack from the new unit.

*i tried the above but with my original power pack but it would not power up, thats how i know its defo dead.

*the key piece as mentioned above is the circuit board that connects direct to the button assembly, i hadnt changed that before because i thought it would not work with a different power pack, how wrong i was.

*so the old buttons, the newer screen and power pack, connect it up, attempt to enter the code from the new unit and the buttons worked as they should.

 

*JUST TO CLARIFY THE CODE ENTRY PROCESS IS

*press the number of the first digit of the code

*press the number of the second digit of the code

*press the number of the third digit of the code

*press the number of the fourth digit of the code

*press ok, then ***** off the neighbours yelling in celebration like whats his face from madagascar when he creates fire.

 

clearly i was unlucky having two faulty units but thank you to all for your suggestions, 

 

as a side note, if anyone has this radio and it does not power up, you might find your car battery starts to get drained, mine did, within a few days it was dead, it took me weeks to work out that the radio was drawing power and i was unable to turn it off because it was never on to be turned off, the only way to stop it draining the battery was to disconnect the radio from the power supply. then get a newer radio and have the ball ache that i had.

 

anyway job done, thanks again.
