Google Maps are one of those must have apps - never get lost again!
1.2 GB and that is not the Sat View. Can't imagine how much memory that would need. I was at the lake last weekend and, yep, no maps. So you will need a Data Plan.
Andnav2 is free mapping and navigation software.
You can download it from the android market.
It does need 3G or wifi to actually download and navigate as you go. Both the maps and the routes are provided from a central server.
However, you can create maps for it for free using openstreetmap.org. This has got Europe and California well covered, and various other parts of the globe but not all parts. The process to create and download maps is a little complicated but works. The maps have a lot more detail than most bought satnav software.
You can also create routes and preload them so they work offline - but obviously they will not then re-route if you go off route.
I am using this to cycle across Europe in June July, so have spent some time investigating and creating and downloading maps. But the only caveat is power use.
If you use Google Maps or Andnav on line with 3G as you travel, the combined effect of data transfer and gps really uses up your battery - on a 250mile motorway trip across the UK yesterday, battery only lasted about 3 hours.
I am going to do another long trip using preloaded maps tomorrow, 3G switched off but gps on and see how long battery lasts
