lol...i have already 2 gps 1490 and 3790. I love bigger screen.
my car is not in garage now so i will test it later. but i remember i can pair my garmin to my dashboard car last time so I can hear sound car system clearly without harsh small speaker within garmin.
regarding Android, i love it like samsung galaxy. but it seems there's none of option to have garmin map in offline mode. It should use data line which is very expensive here to pay.

thx
