HI Guys, 

 

Just fitted our new to us Yeti with our Columbus that came from RustyNuts. I have got it in but the aerial location I think is sub optimal. It jumps around a bit whilst driving. 

 

I put it in the same place as in the Fabia (under the dash on a metal support bar) but can only see 5-6 sats when I could see 8-9 in the Fabia. 

 

Where do people put theirs? I'm thinking of running it under the dash and up the passengers side A-pillar and put it in the headlining there. 

I suspect if you put it in the headlining that it'll he immediately shielded by the metal roof.

 

I've not seen the receiver that you're using, but could you not sit it on the top of the dash?

 

Alternatively (though more expensive) install the OEM GPS-capable roof aerial (noting that they come in many combinations of radio, DAB, GPS and phone) and run a cable through the headlining and down the A pillar.

 

 

Hi Nathanio

 

If you imagine the top of the GPS aerial as an "eye", it needs to "see" as much of the sky as possible.  The more satellites in view, the better the position accuracy, but if you can see at least five then that will get you within roughly 50 metres which is normally enough for car navigation. The software will then "snap" you to the nearest road. Bear in mind that the satellites are constantly moving, so the number you can see and their positions will vary at different times of the day. 

 

Large bits of metal will shield the signal, non-metallised glass and thin plastic are more or less transparent to the signal. So the best place for the aerial is outside on top of the roof.  More realistically for a retrofit, the top of the dashboard in the centre (near the base of the windscreen) will give a view of about half the sky and normally works quite well unless you have a metallised or heated windscreen.

I had my Amundsen RNS315 retrofitted when I bought my Yeti from my local dealer. They used a contractor who specialise in satnavs for VAG cars. They installed the aerial about half way up the driver's A pillar (forward of the airbag so as not to obstruct it). It works well. Never get any drop outs.

That's very true. I had a brain fart there! I was thinking maybe put it under the top box but attached to it. There's enough cable length.

I am getting skipping between roads when they are near to each other. I'll take the wife's car on Friday and see if we are still experiencing it.

I'll give that a go. Thanks.
