Asking this question in many places, trying to get good feedback.

Never had the cable driven speedo close to accurate, so looking at the GPS. Not cheap, so wanting as much info as possible before thinking about pulling the trigger.

Looking for antenna location, accuracy, setting ODO, and more.

Got one not using?

FWIW Just added a GPS Speedo. Put the antenna where I had the entertainment system one. That always gave me excellent reception.

Instructions

361193


361192


Most of the guys just put it up front under the cowl. It has a very long lead so I said why not, don't use the other antenna anymore, phone takes up that slack.

Install is cut the hole & follow the wiring diagram. That will get the speed. Mine also has a momentary contact switch. You can mount the switch anywhere the wire will reach. Mine is under the dash on the bottom lip.

361194


The switch controls functions like 0-60 timing, 1/4 mile, clock, altitude, direction etc. That info, one thing at a time, shows up in the window at the bottom.

I just put it under the dash on the passenger side. Works as it should. I will say, the features built into the speedo will have you out on a country road trying all the options. At least that's what a friend told me. :cool:

I've noticed a slight difference between ground speed and GPS speed on steep grades with my daily driver. While cruising at a constant speed I've noticed a 1 to 2 mph difference at highway speed. That's not much but it's something you might need to be aware of if you are in an area where there are speed traps.

I installed one to solve a sending unit problem at the transmission. Very happy. Works a charm. Since the body is fiberglass the antenna can go almost anywhere. Mine is in the trunk. Doubting friend asked "well what if you lose satellites in a tunnel?". I replied well I get slightly poorer gas mileage and put slightly less mileage on it. Besides, maybe it is better I don't know how fast I am going when listening to that explosive orchestra in a tunnel.

I have also had very good results with mine...matched it with my phone GPS and both speed readings were the same. With the hot start wire connected, satellite acquisition is also quick (even in my northern locale). Good Luck!

Tunnels.... Nearest highway tunnel to me is probably over 6-7 hours away. :D Out here on the wide open plains, the GPS works great!

What about putting the antenna on the dash? Will the windshield cause any problems?

Appreciate the comments, I'm probably going to install. My car, I change tires between street and track, so always different readings.

And, have to make sure I buy the kit: speedo and antenna.

You can put the antenna anywhere. Why would you put it on the dash? Stick it out of sight under the body

So what brand and part number do you suggest? Can the speedo be purchased without all the other gauges. My speedo is working fine currently but I've had to replace the cable more then once.

Evidence...don't speed, they could be watching you with a rig like that. some satellite system has a log file with your ID and knows where you went, and how fast you were going.

our cell phones already do that. i'm trying to stay off the grid.

Interesting though...

I use this.


Works fairly well, easy to install. BUT, it doesn't read anything at speeds <37mph. I don't know why. So, I'm not totally happy with it.

It also won't take the place of your cable. It only works on electric gauges.

I have an Autometer GPS in my 73 Bronco. It works well, but takes about a minute, after I pull out of the garage to “acquire signal”. My sensor is mounted on the dash.

Looking deeper, which GPS sensor has everybody used?

I see the Autometer and Dakota Digital, Summit, others?
