gps speedometer

[342Stroker]

I'm in the process of changing my original MK3 speedhut speedometer to the gps upgrade. I like the pic in the thread placing the antenna on the PS windshield support. Speedhut recommends placing the antenna where it has a clear view of the sky. Does the hood interfere with reception when place in the location shown in the pic. Thanks for any info.

I placed mine on the windshield support on drivers side, works fine.

No issues with mine on the passenger mount.

The fiberglass doesn't affect the signal. As many have said, that location works fine. A different body material, e.g. metal, wouldn't be the case. I now have 10K miles between the Roadster and now the Coupe with the antenna in a similar location under the body. Other than a very occasional dip when going under a freeway bridge, the GPS speedos have been flawless. Given that there's no speed sensor wiring or calibration required regardless of transmission, rear diff, tires, etc. they're an excellent setup based on my experience.

I have 2 cobras with the GPS Speedometer and have absolutely no problem with either, other than a small bump on needle when going under over passes. The features alone are worth the install. Clocks your zero to 60 automatically, Quarter mile automatically as well as many other features. I strongly recommend it. Easy install and no cable to run. What's not to like? I have run my cars through local radar locations and the speed is always right on with the radar read. Not sure what he means by speed catching up? Even if it did catch up, how long are we talking about? Micro seconds?

I have mine mounted same as EdwardB....no issues for me. Seems to acquire signal quickly. I am up in Canada (Winnipeg area) and have taken my cobra 2h north into some pretty heavy bush country, have not noticed any signal drop or lag. Have played with the 0-60 features and 1/4 mile times. nice little feature to have incorporated into the speedo....tough to get it to hook but that's not the GPS's problem.

...and yes when you are doing second gear burnouts, the speedo does not register any speed...

Also might add Winnipeg is roughly 50 degrees N latitude....
