Default Sat Nav not working. after service

Hello

My 2002 Rover 75 2.5 sat nav seems dead, Won't start on on/off switch,
Takes disc into unit in boot,But nothing happens when try to switch it on.
Is there a fuse for the unit in cabin ?
Its the sort that uses Message centre to display data ect
Low level I think.
Any help welcome

Kind regards

John

John,

Ask whoever did your service whether they disconnected the battery.

Depends what kind of service your car had.

Almost certain the service was the cause of the fault.

Yes best get back to the garage who serviced your car and check what they did.

In all the years I have worked my own cars I have never disconnected the battery when servicing - there is no need to, but if they did and didn't ensure that the satnav had shut down before doing so, that could be your problem.

It is one of the peculiarities of the 75's system - damage to the system, I would hardly expect a none specialist garage to know not to disconnect the battery, though maybe on other cars - the radio might loose its code.

Is you unit the one with the satnav controls on a Symphony head unit, if it is please note that the sat nav drive can only be changed by a replacement with the same part number.
The Sat nav drives in the high line setup are different and won't work

Thanks all. for your comments.

I will be in touch with the Garage to check it out.
I think its the Symphony head unit,
There is no red light on boot unit but it will accept disc,
Cant find any mention of fuses in handbook, for Satnav at all.
I'll check it all out,to make sure head unit has power.
Is the head unit easy to get out ?

Thanks All, for your kind help.

John

John; this is significant. If your sat. nav. worked satisfactorily before the garage's involvement, it sounds to me as if they disconnected the battery without waiting for the sat. nav. to shut down first. Of course they may deny this.

It won't be the Symphony at fault.

Simon

I don't see why they would have disconnected the battery? why on earth would you do that to change a set of plugs, oil and filters?

However as it was done by a garage, by definition you won't know, but I would question why a garage would actually disconnect a battery where it isn't necessary
