Using Waze or Google maps to navigate? ...don't forget to download and install Tomtom's free speed and red light cameras warning app. I use it all the time while driving. Couldn't recommend it enough! Let it run in the background while you drive or click the little map sign on the app's main screen (bottom right) and select the consul view. This will display a little floating bar that will seat on top of your phone screen, display the speed limit (on the road you are on) and your vehicle speed and warn you when you get close to a red/speed camera or creep over the speed limit. Furthermore, you can set this app to turn on and off automatically as soon as your phone connects to the car Bluetooth, in other words as soon as you start or finish driving, respectively. Get it, you can all thank me later. https://play.google.com/store/apps/details?id=com.tomtom.speedcams.android.map P.S. When it comes to roads speed limits i find the app to be accurate in 96% of cases. Still good enough and way better then having no warnings at all whenever you happen to creep over the speed limit.
