I have a 2011 focus titanium x and one day my battery died and the aa came out to jump start me and since they did my radio and display screen will not work. All fuses are ok everywhere in the car. Obviously now cannot also use the parking assist nothing. Don’t know what to do and ford want over £130 just to investigate. As said it’s showing an error on the system when they plug in. 

Regards

Tony

Did they say what the error code was?  Do you have Forscan?  

I don't suppose you know anyone with a Mk3 Focus?  Cheapest thing to do would be swap the fascia screen with theirs to see if it's the screen or the radio unit at fault.

have you tried disconnecting the battery for a few minutes.

Hi Tom forscan what is that? No I don’t know anyone with mk3 all they said was communication error 

jump starting the car has spiked the screen most likely.

FORScan is a DIY diagnostic system, which is almost as good as Ford dealer systems.  It's free but you do need a laptop or smart phone, and either an elm cable or wireless dongle which are around £15 now I think.

Communication error just means something's not working, very vague code unfortunately.

Without knowing anyone to swap a screen, you may have to just bite the bullet and buy a used one of you don't want to pay for Fords investigation.

Ian suggested the jump start spiked the screen and I've seen exactly that happen a few times on the Facebook groups.  Tbh I'm amazed the AA still jump start modern cars as it's really not ideal with all the sensitive electronics.

We jump start vehicles at work all day, I probably see 20 a day that come in after jumping to be put on charge. . Fortunately most of the time they are lucky. Sometimes the bcm gets fried or a screen or two.

The screen is probably interchangeable but that unit doesn't have sat nav which I would guess your X model does?

Fair enough then.  I wouldn't think it was worth the risk if you've got to pay for the ones that do get fried lol.

Why do you have so many not being driven?  😮 

brand new sat in compound up to 12 months waiting to be sold. 

Ah I see, I thought they only delivered them once ordered or pre-reg'd.
