'06 A6 Sat Nav Fix?

[charge]

I need help with my nav. Either the yanks have turned off the satellite's today, or my system is on the blink.
To be fair I havn't used it for a few weeks over the christmas period, but tonight, just as a matter of course stuck it on incase of traffic on the A12 from Galleywood to Witham, and it said I was at potters bar, then when I tried again I was at St Albans, then Luton. When I checked the nav info it showed I was recieving no satellites, so on arrival at Witham checked that someone hadn't swiped my shark fin, but it was on the roof untouched (with no snow incase you are woundering). Did exactly the same coming home.
I don't drag snow off the car as i have a hot tap with hose in the garage to remove it to save scratching the car, so I havn't damaged the ariel that way.
Any ideas or should I start loosening the belt ready to drop em at the dealers?

I've had odd problems with Audi electrics in the past in the cold (DIS display flickering) so it could be something along those lines and might be worth waiting until the weather warms a little first to see if it gets better. Otherwise I imagine it's not going to be a common fault so the dealer won't have that much experience with it so you might want to take a horse bit with you to bite down on.

Is it an Avant and has the rear screen wash jet played up at all lately?

[charge]

Yes, it is an avant, but cant say I have noticed the washer playing up, but I am sure Audi did some work on it last year as part of recall work.
It hasnt worked in the recent cold weather though, thought it is probably just frozen?
I assume that water getting to the anttena would upset it.
I can feel my belt getting loose again!

is it NavPlus? Have you checked your satelite reception in the settings menu? Could be a dead gps reciever. Common on the A6.

It is satnav plus, when you go to 'satellites received' it says 0.
So it must be the receiver right?

See if the rear washers working, if its not then the pipe may have come adrift in the N/S boot area where the navigation unit is. If so then your units probably full of water and therefore foooked!

Have seen a few lately as a direct result of frozen washer pipes

Just looked, all is dry in there, still showing '0' for satellites recived.

[Tame Technician]

If the screen and everything works MMI wise, then its not water in one of the modules.

If it says 0 recieved its an antena problem.

Make sure it hasnt come unpluged, if its pluged in, most probably needs a new antena, we've done one or two for this.

[ecain63]

As i suspected. Whip the NavPlus out and check the antenna is plugged in. If it is then you know its fooked. Either see Audi for a wallet raping or find an aftermarket reciever with the correct fitting and you'll be laughing.

NavPlus is crap at the best of times so may i suggest an upgrade. RNS-E, Pioneer (mine is ace), Alpine or Kenwood.
