Can anyone explain to me benefits of running Brut Maps? I am basically looking for GPS navigation where no cellphone signal available. Will Brut Maps help me achieve my goal? I installed Brut Maps, but it seems just like the regular Google maps and it seems to require data connection (I was on the phone when I tried it first time). I am going to Europe soon and I would like to have a mapping/gps capability there without Roming at $3/min for data connection. Thanks.
