Help Wtd With Ford Sat Nav System

[corskey]

My factory installed sat-nav system fell sick last week. On my way to a job interview it lost its position, and the positioning progressively got worse.

 

On my way home, I managed to tell the system where it was using the manual positioning option in the settings menu. It was even receiving signals from up to 4 satellites. So I thought that I had cracked it :blink: :o .

 

However, it looks as though it has died again. The position is again lost. If I manually program in my position, the navigation works, and I can find my way home again.

 

However, If I look at GPS viewer I see that although 29 satellites [29 never changes???] are available I am receiving none.

 

anyone here got any ideas before I leave it with the local Fraud dealer.

 

Please help

Probably a broken wire between GPS receiver and head unit - or a loose connector plug. Try taking the unit out of the dash and checking the wiring before visiting an in-car audio place - then risk a visit to the dealer!

Good luck

I dont suppose that U know what the cable looks like.

 

I've been unable to remove the head unit, but when I look under the console I can see what looks like a (4mm??) co-axial cable with a screw fixing hanging in space.

 

I can't remenber anything like this last time I had the head unit out, so it could just be the poor installation of my DVD amd PS1. Let's hope that it's the cable between the receiver and the unit.

 

Nope - got the head unit out and that doesn't fit anywhere - looks like the reminants of the car-phone kit :lol:

 

anyone got a wiring diagram for the Ford head unit (I've photographed ths back, but I can't upload)

 

Cheers

that wire hanging , wouldnt be an earthing wire would it? any small holes nearby where you could screw it to earth and see if it makes a difference ?

no m8

 

it's the wire from the telephone aerial from where the telephone kit used to be.

 

I've had it to an car alarm & radio installer, who reckons that the connections from the receiver to head unit are OK. His diagnostic is that the fault lies with the head unit. A quick check with a working unit will prove this diagnostics, now I just need to fing a working unit????
