Sat Nav Problems

[richards38]

I have a 75 Cdti with the low line sat nav which is not working although the radio does. When i press the on butten on the header unit in the car nothing happens. Could anybody let me know if i need a new headr unit

First check that no water leaks have got onto your Sat Nav Computer.
Leaks Can get in through side trim panel on Tourer or Rear Glass seal.
If thats OK, and unit is dry,
following correct shut down procedures.
Disconnect Battery for 25 - 30 Minutes then re connect.
Could just hopefully need a reboot.

Tried disconectiong the battery but still not working. When i reconected after leaving overnight the radio did not ask for the code is there a battery memory backup. As far as i can see the computer is working ok no water

The Radio unit does not have any code for it.
Also try removing Map disc and reinsert. (you may well have tried that to)
Where is your location in case you are close to me for testing of Unit?

The low line unit can require a radio code but depends on if it has been set up on the head unit

When you switch it on do you get anything at all on the LCD screen.
Have you checked the screen is ok by pressing the trip computer to scroll through the display options such as Range, MPG etc.

Does the red light come on the computer when you switch the car on or open the boot and can you hear the cd spinning ?

the screen works ok. There are no lights on the header when i press the on switch

Thanks for Info.
I've never come across one with a code on,
so wrongly made the assumption it was the same as Hi Line Sat Nav system.

The only reason I know is my car used to have the lo line system fitted and when the battery went I had to get the code from the dealer

When you say the header do you mean the LCD screen or the Radio head unit ?
Does your radio unit look like the picture in this thread ?

Does the red light on the nav computer come on when you switch open the boot and if you leave the car for a few minutes without locking or unlocking the car or opening or closing any doors does the light go out ?

Have you had the radio out of the car for any reason as it may be worth checking all the connectors at back of radio head are correctly plugged in.
