In car speedometer
 

Hey so weird question... anyone have any speedometers/app/program/tool that can track both MPH and KMH with certain accuracy?

Reason I'm asking is because I'm going on a road trip and just realized how the MPH lines are not scaled properly. ie the 60mph is aprox 90kmh (it should be a tad under the 100), plus my having slightly different sized tires, I just don't want to be caught with my pants around my ankles when I'm in the states. :bowrofl:

Use GPS.

A phone app maybe?

how accurate are they? reception in remote areas affect quality/ability to decipher?

lack of reception seems to be the biggest drawback.

When I've traveled to Canada for work before I've always used my GPS to give me my speed in km/h. On the drive from Windsor to Brantford I didn't have any issues. Also never had any issues with accuracy in remote areas. Only issue I've ever had with my gps is in big cities where skyscrapers, tunnels, etc. block the satellite signal.

I use a GPS app on my phone from time to time on my phone - (digihud) , only when going through wooded areas or canyons should the signal be compromised , they are considerably more accurate than the speedometer

A lot depends on the GPS unit. A good one can be very accurate, especially when averaged over a few minutes at highway speeds. If it were me, I'd run down the road at different speeds and compare to dash speedo, then just use the speedo, making corrections in my head.

GPS coverage is (usually) a lot better than cell phone.

thanks for all the feed back.
leaning toward a GPS unit with a speed tracker.

or I might just write a note of x kmh = y mph by doing some testing now :roflpuke2:

Phone GPS should, honestly, be good enough. Your speed isn't fluctuating much at highway speed so you should have an accurate reading after a few seconds.

I use WAZE traffic app and enable GPS display
Works pretty good and Its pretty good at telling you were the Cops are and traffic

in the states the speed limit is usually 70 on the interstates... go 120-130kmh and no one will bother you at all. on the highways you can do 110-120kmh and again shouldn't be bothered.

whenever i drive to canada i always forget it's in kmh and one trip i drove 100mph where it was 100kmh. i was wondering why everyone was driving so slow :rofl2:

My Passport 9500ix is pretty accurate. And I can switch between miles and kmh.

Phone GPS and consumer GPS units use the same chips and radios; you're not going to see any difference between the two as long as the phone's processor isn't too slow to run the OS (ex iOS 9 on a iPhone 4); you could get app freeze and the display could fail to update.

I use Waze as well for traffic and smokey reports. Its speedometer is plenty accurate and suitable for staying legal. Network coverage doesn't matter, the speedometer is calculated using GPS alone.

how's that on the data consumption?

if you got caught with our new 'stunt driving law' you would be in the pooper for 7 days... impounded, suspension, big fat fine and lots of other problems :(

I always joke with our signs that are 60 MAX. so that's 60 mph max?!?!? lol

yea I have ball park figures of what converted but my concern was variance which i'll have to work out.

awesome... i'll take a look at that too!



thanks for the input everyone... last thing I want is a us ticket and bond to worry about :shakes head:

GPS does not use any data. You can shut the data off completely and GPS apps will still work.

Use Waze - it has a speedo on it.

My 9500ix also has GPS with a speedo - it matches Waze exactly.

Neither of them match my speedo on the car above 65ish.

But remember, if you're going through Virginia, radar detectors are illegal (if you have/use one). They have radar detector detectors and ****.

Even if it's off they'll still take it if they see it (so I hear).

******* fascists.

If you want the real time traffic info (cop reports, slow downs, etc) it absolutely requires data.

if you read what I said really carefully, I said GPS. The functions you mentioned are non GPS functions. They telly on GOS, but no effect on its functionality. GPS will work just fine without them.

Anyway,if you are going to another Country,try to keep below the Country's speed limits,do not speed,the drivers there usually will 'forgive' you,because your licence plate are different...

We don't. We ******* hate Canadien license plates down here (Phoenix).

******* snowbirds. GO HOME.

<3 u Mishuko.

Get a bluetooth OBDII adapter and run Torque (android app) :twocents:

Lmao, no blue hairs!

i thought most navs who actual speed in the screen? then set cruise.

im not sure about virgina, but most USA roads ive traveled, cops arent dat anal about ur speed unless u're going like 12 over on the hwy. be careful in small towns (pop less dan 5000), residential areas, school zones, construction zones. fines are huge for the latter 2.

Virginia is very anal about speeds.

Use a bluetooth OBDII adapter and an app like Torque to read the speed directly from the ECU on your phone. No GPS involved.

should really put dat funding towards other serious problem areas, huh?

I don't really know what their beef with traffic laws is all about but yes, there are better things they could be doing with their resources.

Still though, I make good use of cruise control when I have to drive in VA to make sure I'm always legal. They'll bust you for a mile over the limit, just because they can.

I can't read! Lol yea I reread it all. . Makes sense.

My touring z has no tech package. But generally construction and school zones I'll slownright down. Double fines here and cops are always there.



I'll keep that in mind.... that's part of the reason I want something as super accurate as possible for live speeds



Torque app off obd sounds best

As far as accuracy, the iPhone and most phones update at 1 Hz (so one time every second). You can get an external GPS module that connects via Bluetooth to provide a more frequent update rate. The one below updates at 5 Hz and will give you just about all the accuracy you need. It's also useful for timing at HPDE's and track days.

You just hate old people and how they drive. Not necessarily Canadians (I hope).

:icon17: You're correct.

It's just more fun to generalise. ;)

Yeah over here on the west side of State a lot of Canadians winter here!

If you live anywhere north of Toronto (everywhere else) you will understand the hate of winter lol
