Sat nav & Heated screen

Hi all.

Does anyone know if the heated screen in a D3 would affect my 3rd party sat nav ? I don't use the inbuilt nav in my 2005 SE as it's out of date, so I have a TomTom start 60 & a Garmin Nuvi, neither of which seem to be able to acquire a valid GPS signal when stuck to the inside of the windscreen (centre bottom) Even if I drive for an hour or more, no luck.

If I sit them outside they find the GPS satellites oK after a minute or two.

I'm thinking that the heating wires in the windscreen may be somehow shielding the signal ?

Thanks

Mat

Had the same in an earlier D3, just run a GPS aerial up the passenger pillar to near the top of the screen (should be just outside the coverage of the heated elements) and you should be good to go..

Thanks for the reply. How does the GPS aerial attach to the sat nav ? I don't see a port or connector for an external aerial ?

Thanks

It depends on your version, I'm not sure if the earlier/lower spec versions had this option, there was an external aerial connection socket on the one I had..

At the edge of the windscreen is about 3 inches where there is no heater.
You could try putting it right in the corner

I use occasionally a TomTom rider in my HSE with heated screen fitted… never a problem
Used it from italy till the UK till Tjechie…

Use it in the bottom/middle of the screen… works within a few meters, every time…

When did you update the maps and maybe more important the system software? They do need new satellite position info updates once in a while…

No correct satellite positioning updates and you get these issues, because “it” looks at the wrong position..
Been there…

Edit: i just see yours does work outside the car…… stil maybe an update does fix this…
