Sat Nav Accuracy Issue

[Prodigy]

I have noticed that when i am viewing the map screen on my RNS 510 my vehicle location is approx 50 - 100m behind where i am actually situated.

Anyone know what could be causing this? Is there a way of recalibrating?

I can confirm i have sw version 2760 & V3 maps.

My experience is the same. In saying that, was the same on my last car as well (Lexus IS250 Sport Luxury)

Is yours factory fitted or aftermarket?
Mine is an ebay purchase so I'm considering changing the antenna and seeing if that makes a difference.

Mine is factory fitted.

is this when you are moving or stationary??
When i am moving the maps certainly lag a little in distance ... i always thought it was an inherent lag in the gps where it takes time for your position to be relayed to the satellite and then back to the car to update on the screen etc so in this time your car has already travelled 50m or so causing an apparent shift in your actual position etc.
when stopped my position is pretty close to being correct on the screen.

It's most noticable when im moving.

From my research it seems to effect some people and not others. Sounds like i may have to just get used to it.

Mines very accurate, even when I'm driving.

where did you place the antenna?

where did you place the antenna?

Above the centre vents, directly under the dash. This apparently is one of the best places to put it on the Golfs.

Thats where i placed mine and honestly mines within a few metres even when driving, and i have the same firmware 2760 version 3 and RNS510 C. Is yours sitting on the metal cross bar directly above the unit ?

It's above the centre vents on a pastic surround from memory. Nothing above it except the dash itself.

have your car tinted? try to temporarily place your antenna out side the car (eg: on roof) to check it worked or not.

The antenna is directly below the windscreen which isn't tinted.

I have a new antenna on the way so will see if that makes a difference once fitted.

Good thread, even though (unfortunately) its causing you some grief prodigy.

Curios to see how it turns out as I'm thinking of getting the same one off eBay as well.

Hopefully it resolves your location issue. Keep us posted and good luck!!

Fitted mine a few weeks ago and am exhibiting similar traits. Anyone able to fix this issue?
