Depends on which bike you want to fit your Sat nav. For some there are factory options, or you can get a a ram mount. https://www.ram-mount.co.uk/?gclid=EAIaIQobChMIrfjHqb_D2QIVDZPtCh22BA_CEAAYASAAEgI8Q_D_BwE Or you can easily make something yourself. I made a mount for my Garmin Zumo 595 and used the really nice adjustable bracket for the Multi Strada 2015. Its not available as an assembly but all the parts can be ordered.
I tend to run Waze the whole time in my car, even when I’m on familiar roads. It’s saved me so much time and points over the last few years.
