GPS mapping for Android

you can get OSM maps for free..from the OSM wiki
http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/Download

I use the openmtb ones rather successfully for multiple countries.

route wise you can use pretty much any mapping software/website you just need to get it into the right format - read up, this thread has a lot of info about that.

Thanks,

So you can create your route and then upload it to the etrex.

Just one more thing before I commit to buying it;

what about if your out in the middle of no where and need to find your way home, will it come up with directions on the fly also?
