Car Play and waze

so I just did a trip in my 18 Limited. I had Waze hooked up through car pla via USB. I noticed when Waze is hooked up the GPS speed on the Waze app was 15 Mph faster then my Speedo in the car. If you unhooked the iPhone from USB and restarted the app without it hooked up and the Waze app was matching my Speedo. Plugged it back and the app was indicating 15 mph faster. Did it numerous times. Not sure what was going on.

I noticed that too, but just in the last couple of days...and I’ve been using Waze with CarPlay since it came out last year. I suspect it’s a glitch in the newly updated version of Waze that will be corrected in a week or so with a new update.

Is it Waze or Sync?

I use an app called Speedometer and it was showing the same 15 mph increase.

This just started happening on the last week. Annoying as the speedlimit is always blinking red.

Just wanted to reach out cos my Waze shows also this, dont call it a glitch, its a BUG....

If you check out the Waze forum there are a LOT of folks complaining; seems to have happened in the last week or so. Many of those complaining are using Sync, but I’m not sure if they all are.

Oh well, they’ll get it sorted out. In the meantime I’ll just have to use the giant speedo in the gauge cluster.

I just made a cross country trip and noticed the same. Found the below info.

I also just updated my Sync 3 to build 19119 via USB. Will be on the road in about an hour and will report back if it’s fixed later.

I used this link found on another forum and the update was successful.

Note: Ford cars with Sync 3 v3.0 & pre-my18.5 (some) vehicles will show Waze Carplay speedometer readings higher than actual & higher than the car Speedometer - when the iPhone is connected to Carplay.
Waze (and other apps with the speed feature) can only get speed readings from Apple's Carplay API and that data primarily comes from the Ford sync 3 system to apples Carplay api.
Current v3.0 sync 3 versions sends inaccurate (higher) speed readings to Carplay - and that's why Waze shows a higher incorrect speed on these Ford cars (eg. 65mph shows as around 76 mph).
The issue lies with Ford and not with Waze. The fix needs to come from a Ford sync v3.0 update issued by Ford.
They are working on an "official" v3.0 update to be released in the future to resolve this. (version number higher than 19000).
So need to wait for that to be released.

Ford cars with Sync v3.3 or higher (my18.5 and newer) latest updates should have this fix implemented.

v3.2+ updates cannot be installed on cars with v3.0 (yet) due to hardware differences.

If you have a Ford car, this is the cause or your issue.

If reporting on Carplay issues you must give info on the iphone model, iOS version, car make and model and infortainment system version to help investigations

I emailed Waze and they said it is happening with many manufacturers and CarPlay as an interface not just Ford.

Speed works with sync 3.0 build 19119!

Downloaded the above referenced SYNC3 3.0 build 19119 and extracted it to desktop. Copied all extracted files to USB drive and my 2017 will not recognize it. Tried extracting files directly to the USB drive and that would not work either. No error messages other than a message of "Indexing files on USB 1" ever appeared on the screen. My Sync 3 version had been updated from 2.3 to 3.0 previously with no issues. For those who have installed this update successfully could please list the install procedure step by step you took that worked.

Edit: USB is formatted as ExFat.

Edit: Finally got it to install. Not sure what I did differently, but it's installed. Now to test drive and see if Waze is fixed.

We noticed the same thing. We put the raptor rims/tires on the wife's and as we were driving back I wanted to see how far off the speedo was. Waze was significantly higher, as was several other apps. My wife tried her phone and we finally got one to work.
