540 and athermic glass

(First post, many times browser)

Hi. I've had a 540 for 6 months now, and been very happy with it. It never lost signal except in the most extreme conditions (tunnels, etc). It would crash occasionally, but nothing to write home about.

The problem is that I now have a new car with an athermic windscreen. Despite other posts I've read saying this is unlikely to be a problem because of the improved sensitivity of chipsets these days, it's certainly causes my 540 some distress.

It now regularly (every few minutes) loses lock and/or starts drifting around the scenery The gps signal is significantly attenuated.

Obviously an external antenna is out. There is a patch of windscreen at the top that seems to allow signal through, but mounting the 540 there seems a bit impractical.

Any advice?

Hi, I have a Citroen picasso which I believe also has a athermic windscreen, I've never had any problems getting and keeping a signal. Maybe it's worth trying it in another car and see what happens?

... or trying the device in a different position within the car.

Mount it away from the windscreen. I also have athermic.

My 930 is down on my centre console via Brodit mount and I never lose signal.

Thanks for the advice.

I've fiddled with the positioning on the screen. It seems a little better in the middle, and a lot better (near perfect) at the top in the middle where there's a gap in the coating. However, it's not very practical up there!

I think the on-dash option looks best, and from other posts I'm guessing that the Brodit is favourite. I'd prefer to not drill holes in the dash of my new car just yet... Surprised

so the ProClip looks good.

One word of caution with the Brodit. I bought a Pro Clip for my Mondeo. It slides between various bezels on the dash. In my case it was rather a tight fit and I recently noticed that one of the bezels has developed a crack as a result of the pressure on it from the Pro Clip. I wish I had used the bean bag which we use on my wife's car
