Testing a CHEAP GPS SPEEDO From Amazon!

In this episode of BUS TECH...we test a cool little GPS SPEEDOMETER we found on Amazon for under $20.00
Will it work? Tune in and find out!
This is NOT a paid endorsement. We would LOVE to have a few of those...( hint hint hint any vendors out there? )...but so far we have bought everything reviewed on this channel so we give it our honest opinion. It's either good or it sucks. We'll tell you straight.
******************
Come along with us as we blunder our way from one part of the build to the next as we turn the old Bus in to one cool Skoolie.
We have help along the way from various desert dwellers in what will ultimately be a bus build and set of adventures all of us can take part in.
Sit back and get an eyeful of a Bus Life Adventure the likes of which you have never seen before and most likely will never see again.

I recently bought a 2006 Jaguar XJ8 that was originally sold into Canada, its rather small speedometer reads in KPH, my old eyes have a hard time reading the MPH band on the dial. This sort of thing would be just the thing to have, thanks for the review.

[@DJBigcOre]

Thanks for the video, I was looking for a cheap speedometer for my space shuttle. ;-) Thanks

[@СпасДимитров-б7х]

Thank you

[@hashwizard2544]

great video

Great Video - Funny watching a "tin hat" assume this takes info from your car

[@Buses2Bikes]

He didn't know how basic the GPS unit was. He assumed it got its info from the car too and not ONLY from satellites.

[@kevinspahr6632]

What does driving a car without a computer have anything to do with the price of bananas in Brazil??? It's a GPS speedometer.......just like the old garmin's that told you the mph you were driving, it works off of satellites...lol. Dude must be high or not too bright 😂

[@kosratonwheels368]

I got mine today It's inaccurate by 1-3 miles how do i fix it

[@Buses2Bikes]

It uses satellites so it's prolly your car that is off and not the GPS /odometer. Might be as easy a fix as making sure your tires are properly inflated so your dash odometer reads as accurate as possible. Or if you changed tire size, that could throw off the car's odometer too. If you're 100% sure it's the GPS Odometer that's off...do you live in a mountainous/heavy tree area? Those features may cause a lag in satellite data/signal reaching the unit and causing inaccurate readings.

[@bryanwadd]

They're designed to over-read the same as a car speedo is. Some of the other 'HUD' speedos (this one is not actually a HUD) available allow you to adjust the over-read percentage but this one doesn't - I have one. Just because it is GPS, doesn't mean it's a true speed, it depends how it has been programmed.

[@Buses2Bikes]

@@bryanwadd Well...it matched our vehicle's Speedo so WIN/WIN

[@kosratonwheels368]

@@Buses2Bikes it's very tweaky it bounces around it's never even close to accurate i finally got an obd one turns out my odo is actually off by 3 miles but still I'm more comfortable with the obd cause it has many features

[@VashthStampeede]

​@@Buses2BikesFine except when you buy two or three that don't agree with each other while plugged into the same car. Kind of shakes your confidence.

These Speedos are programmed to over read by 4%. If you want "accurate", this is not the one to get.

[@Buses2Bikes]

Except it perfectly matched the speedo on our car. When we were doing 50, it read 50. When we did 65, it read 65. It always stayed 1 mph during up and down travel speed and we settled on a MPH and stayed there, the GPS Speedo matched our speed reading and stayed steady. Watch the video.

[@thunderballz74]

Folks get these because their speedometer crapped out.. like my situation and right now I cannot afford 120 bucks for a "used" instrument cluster for my car. Just something to be within 2 to 3 mph of speed limit

[@Cornerer1]

@@Buses2Bikes Production speedos are designed to overread as well so i guess this makes sense. May I ask how was the delay under hard acceleration/braking? I can live with slight over read but not delay.

[@Buses2Bikes]

@@Cornerer1 From what we could tell it either under-read or over-read for only a couple of seconds when we changed speed. And that we figure was the lag time for the satellites to ping back with the correct speed. But again, it was only 1 MPH up/down for a second or two than it read correctly again. For $20 I think that is acceptable performance.

[@bryanwadd]

@@Buses2Bikes Satellites don't ping the speed, that's not how it works. They send a constant stream of packets of data with a time stamp in them which the GPS speedo picks up. Getting enough of these streams of data from multiple satellites enable the unit to calculate position, and therefore distance from one position to the next (if you're moving), and therefore speed can be calculated when time from one position to the next is taken into account.
