Getting around the athermic windscreen problem

[DeLorean]

If you have an athermic windscreen, you can use an external antenna without having to stick it to the outside of your car

On my Renault Laguna II Sports Tourer there is a section either side of the rear view mirror that does not have the metallised layer.
This is area is designed for toll tags and automatic door transmitters etc…

Run the cable through the dashboard, up the door pillar rubber, under the front of the roof lining and stick the external GPS received in this area using a black outdoor sticky pad (stick reciever facing up, not up-side-down).

By doing this, my wiring is completely hidden.

I’ve been using my antenna in this location since I had a TomTom Go 300 years ago and I get a fantastic signal all the time

I hope this helps someone.

P.S. Unfortunately you're screwed if you have a TMC reciver as TomTom generously only give you a few centimetres of cable

P.P.S. My Trumpion is completely unaffected by athermic windscreens

We've mentioned this many times previously Often the lower left and right corners work fine too.

Thankfully the issue of athermic windscreens affecting reception is rapidly becoming a thing of the past. With the advent of SirfStarIII and newer receivers it is no longer a problem.

Yeah, I know we've covered this subject many times before.

I just thought someone might find it of use

There are still a few people out there who are new to all this GPS stuff
