Faraday cage car

[Robbo1961]

I want to buy a Tomtom but my car is like a Faraday cage. I am looking at spending up to £200. Which sat navs have an external antenna adaptor that I could purchase in my price range.
TIA Paul.

German vehicle (e.g., Mercedes S and R class) with the metal oxide material (athermic coating) in the windscreen? Seems they're the few that continue to use it. Messes with radar detectors and toll transponders, too.

Don't know of any 'consumer' GPS made today for in-vehicle use that includes an external antenna jack.

Due to some silly rules about RF in the UK, re-radiators aren't legal (at least they didn't used to be), but that's the only solution in this sort of situation. However, I've heard that these work ...

I have an antenna. I want a Tomtom (or other satnav) that has an adaptor that I can plug it into. I used to have a Go 500 which had an antenna adaptor but I am looking for a more modern satnav which has one.

None of the newer models have one.

Maybe support can help:

To repeat, Don't know of any 'consumer' GPS made today for in-vehicle use that includes an external antenna jack. Your alternative would be a unit as shown above.

What vehicle are you driving? We like to keep track of which models are presenting this kind of problem to users.

Thanks for your help.
I might end up using my Garmin GPSmap 62s that I use for Geocaching then. That has an external connection.
I have a Vauxhall Astra Bertone. 2.2L

Yup. As noted, I know of no "in-vehicle" unit. If a 62s would give turn by turn street name instructions, you'd be good to go! Don't know what you own for maps, but take a look at http://garmin.na1400.info/routable.php. Might save you a few bucks over the price of the Garmin maps. I run those on all of my Garmin handhelds in addition to the odd topo map.

Didn't realize that Vauxhall had nasty windscreens back when the Astra still came as a cabriolet from Bertone. Will add that to the list.
