Navman 3000 & Ipaq 3870

Can anyone tell me whether I can use a re-rad antenna in a car without an athermic windscreen or will it cause problems. My setup has been working great on TomTom Nav 2 until a couple of weeks ago when the Ipaq died overnight. It lost everything and I had to reinstall every application from scratch, since then the GPS location dances around the screen as you drive down the road. It cant seem decide where I am. I have a re-rad from my old Laguna but am worried that it may fry the receiver or give it false signals.

Any advice???

Steve, first of all a reinstall of TomTom won't cause problems with GPS Signal, so I suspect you either have the wrong driver selected in TomTom, or you are using SiRF. If you are using SiRF, switch to NMEA.

Using a Re-Rad in-car without a UV coated windscreen will still work, but it will only increase signals if signals are being dampened, there's nothing to suggest anything has changed in your situation, so really a Re-Rad will not help.

Have you moved where the GPS sits ?

Thanks for the advice. I found that the TT2 software was still installed after the Ipaq had seemingly lost everything, I then re-installed TT2 again and this was causing the problem. Everytime I started TT2 it was trying to run two copies at once causing all sorts of conflicts. I uninstalled both copies and started a fresh. I now have a perfect lock and very accurate positioning. I did install my re-rad and now get a 9-11 signal strength constantly. The windscreen on my Volvo V70 is clear so the antenna should be receiving signals from both.
Thanks for your help.
