using my phone sat nav today

[#1]

I use waze every day about 300 miles a week, I'm a light data user elsewhere as most places have wifi, but only use about 300mb a month

They will all use very similar amounts of data.

Get "Here" (was Nokia maps) from the Play Store and download the maps via WiFi, then use the Offline mode to reduced  mobile data use to zero.

@johnstilwell is here still free on Android?. I use it on windows phone and it's pretty good and as you say no data when you have downloaded it.

@bfairchild 

Yes it is 100% free, I have it on my Android and its damn good

Google Maps will use the most data.

The 2 apps that have the maps stored on your phone don't need any data,you could switch your data connection off and they will still work but Google Maps uses data to constantly download maps as you travel.

As mentioned above,Here Maps is an excellent app and if you have access to wifi you can download the UK map to your phone and it will need no data to operate.

nav free this is a free sat nav which doesn't use data or wifi before you set off on your journey download it , this has been a life saver for me try it you won't regret it .

I used Google maps the other week to drive a 660 mile around trip. It used just over 800mb of data 

Normally I stick to CoPilot although it's paid for but does offer offline mapping. Not quite a smooth looking as Google although it does give speed camera warnings. Played with Here Maps but didn't feel quite as nice.
