Be careful when using Waze full time, I used to use it (and a different app for driving trucks) on my old phone, and after 2 years, it burnt the HUDs into the phone screen.
For that reason alone, if you're a heavy satnav user, buy a stand alone unit. If it is occasional use, it should be reet.
Thanks. I'll bear that in mind. Fortunately I only use it in other people's vehicles as a get out of jail. I won't have it on my personal phone - I won't allow many apps on that as they nick too much personal data - but my work phone is partitioned so it goes in the sandbox side with the rest of the intrusive junk.
