GPS antenna location?
 

My wife and I are experienced GPS users (geocaching, survey markers, etc).

We've noticed that the Escape Hybrid roof is thick enough to block our garage door remote control. This made me wonder where the GPS antenna for the navigation system is mounted. Does anyone know?

Someone said it was under the little recessed square on the top of your dash in the middle near the window. But I have no confirmation of that.

I'm not sure about the FEH, but my 07 MMH has "an antenna" on the right side just front of the passenger door that I thought was the NAV antenna (since the FM antenna is usually etched on the liftgate windows, right?)

Here's a picture of the 07 MMH that has that antenna...cant see it in this picture, but it's squiggly, almost like a double helix, and not normal straight FM antenna at all.

Thats your FM antenna.... the only thing on the liftgate is a defroster.

Oh..ok. Thanks for the correction. So where is the FM antenna for the FEH? Is it telescopic? If so, why the heck did they make the FM atntenna for the MMH non-telescopic? Inquiring minds wants to know...(ok...I'll read up on my manual tonigh).

Hi Lloyd

The GPS antenna is behind the Navi which has to be removed to access the antenna. It is held in place by one screw. I thought I read it was part of the Audio Control Protocol module, but it's not.

GPS is a very faint signal, and needs to be pretty much line of sight with the sky.

It will go through thin ( 1/8" ) plastic or glass, but sheet metal of any kind is a formitable barrier.

I've been suspicious of that little plastic square ( or rectangle, not looking at it now ) in the center of the dash, near the windshield. I can't confirm at this point, but other than the outside of the car, this would be the logical place. ( also close to the back of the Nav unit itself )

IT IS POSSIBLE ( but improbable ) for the GPS signal to be integtrated into the AM/FM whip antenna on the outside of the car.

Re: GPS antenna location?
 

I doubt that whip antenna would be of any use for receiving the GPS signal. While both are LOS signals, the whip antenna is mainly used for AM signals which are medium frequency (300-3000 kHz) IIRC. FM which is VHF (30-300 meg) comes in pretty well without the whip even installed. GPS signals are way up in the UHF band (300-3000 meg) I believe.

I think you missed the point. One antenna could serve multiple purposes. This is almost certainly not the case here, but could be in the future.

FWIW, GPS L1 Band = 1575.42 Mhz Wavelength = 19.029cm ( 0.19029m ).

Or 1.5 Ghz in round terms.

Hi Ray

If you look on top of the center of the dash close to the winshield, there is a 1 1/2 inch square plug. Pretty sure that that is the top of the GPS antenna. The shop manual says the navi has to be removed to access it. This location would give the antenna a clear shot though the windshield. It looks like the brackett that holds the antenna in a horizontal position is bolted to the firewall.
